Wavelength to Frequency Calculation and Equation
 A simple equation relates wavelength and frequency to the speed of the wave.
The wavelength to frequency and frequency to wavelength calculations are important in physics and engineering. Here is the equation relating wavelength and frequency, example calculations, and a table of common values.
Relationship Between Wavelength and Frequency
A simple equation relates wavelength to frequency:
v = λf
- v = wave velocity (how fast the wave propagates in a medium)
- λ = wavelength (distance over which a wave shape repeats)
- f = wave frequency (number of waves per unit of time)
For light and other electromagnetic radiation in a vacuum, the wave velocity is the speed of light (c):
c = λf
But, the wave speed is different for other kinds of waves and for light passing through a medium.
- Light in air or vacuum: 299,792,458 meters per second
- Light in water: 224,901,000 m/s
- Sound in air: 343.2 m/s
- Sound in water (20 °C): 1,481 m/s
Wavelength and frequency are inversely proportional. As wavelength increases, frequency decreases. As frequency increases, wavelength decreases.
How to Calculate Wavelength From Frequency
Rearrange the equation and calculate wavelength from frequency:
λ = v/f
For example, find the wavelength of the musical note A4, which has a frequency of 440 Hz.
The only tricky part in the calculation is keeping the units straight. Usually, you work with meters and Hertz and then convert to other units (e.g., nanometers, THz, GHz). In this problem, the wave velocity is the speed of sound in air (343.2 m/s). The frequency is 440 Hz. One hertz unit equal one cycle (wave) per second, so a frequency of 440 Hz is 440 s-1.
λ = v/f
λ = (343.2 m/s)/(440 s-1)
λ = 0.78 m or 78 cm
As another example, find the frequency of the green light of the aurora borealis, which has a frequency of 5.38 x 1014 Hz.
Here, the equation is:
λ = c/f
λ = (3 x 108 m/sec)/(5.38 x 1014 s-1)
λ = 5.576 x 10-7 m = 557.6 nm
How to Calculate Frequency From Wavelength
Rearrange the equation and calculate frequency from wavelength:
f = v/λ
For example, find the wavelength of orange light with a frequency of 4.8×1014 Hz.
f = v/λ (but v is c for light)
f = c/λ
f = (3.00 × 108 m/s)/(4.8×1014 s-1)
f = 6.2 x 10-7 m = 620 nm

Allegedly, in the fall of 1943 a U.S. Navy destroyer was made invisible and teleported from Philadelphia, Pennsylvania, to Norfolk, Virginia, in an incident known as the Philadelphia Experiment. Records in the Archives Branch of the Naval History and Heritage Command have been repeatedly searched, but no documents have been located which confirm the event, or any interest by the Navy in attempting such an achievement.
The ship involved in the experiment was supposedly the USS Eldridge. The Archives has reviewed the deck log and war diary from Eldridge's commissioning on 27 August 1943 at the New York Navy Yard through December 1943. The following description of Eldridge's activities are summarized from the ship's war diary. After commissioning, Eldridge remained in New York and in the Long Island Sound until 16 September when it sailed to Bermuda. From 18 September, the ship was in the vicinity of Bermuda undergoing training and sea trials until 15 October when Eldridge left in a convoy for New York where the convoy entered on 18 October. Eldridge remained in New York harbor until 1 November when it was part of the escort for Convoy UGS-23 (New York Section). On 2 November the convoy entered Naval Operating Base, Norfolk. On 3 November, Eldridge and Convoy UGS-23 left for Casablanca where it arrived on 22 November. On 29 November, Eldridge left as one of escorts for Convoy GUS-22 and arrived with the convoy on 17 December at New York harbor. Eldridge remained in New York on availability training and in Block Island Sound until 31 December when it steamed to Norfolk with four other ships. During this time frame, Eldridge was never in Philadelphia.
A copy of Eldridge's complete World War II action report and war diary coverage, including the remarks section of the 1943 deck log, is held by the Archives on microfilm, NRS-1978-26. The original file is held by the National Archives.
Supposedly, the crew of the civilian merchant ship SS Andrew Furuseth observed the arrival via teleportation of the Eldridge into the Norfolk area. Andrew Furuseth's movement report cards are in the Tenth Fleet records in the custody of the Modern Military Branch, National Archives and Records Administration, (8601 Adelphi Road, College Park, MD 20740-6001), which also has custody of the action reports, war diaries and deck logs of all World War II Navy ships, including Eldridge. The movement report cards list the merchant ship's ports of call, the dates of the visit, and convoy designation, if any. The movement report card shows that Andrew Furuseth left Norfolk with Convoy UGS-15 on 16 August 1943 and arrived at Casablanca on 2 September. The ship left Casablanca on 19 September and arrived off Cape Henry on 4 October. Andrew Furuseth left Norfolk with Convoy UGS-22 on 25 October and arrived at Oran on 12 November. The ship remained in the Mediterranean until it returned with Convoy GUS-25 to Hampton Roads on 17 January 1944. The Archives has a letter from Lieutenant Junior Grade William S. Dodge, USNR, (Ret.), the Master of Andrew Furuseth in 1943, categorically denying that he or his crew observed any unusual event while in Norfolk. Eldridge and Andrew Furuseth were not even in Norfolk at the same time.
The Office of Naval Research (ONR) has stated that the use of force fields to make a ship and her crew invisible does not conform to known physical laws. ONR also claims that Dr. Albert Einstein's Unified Field Theory was never completed. During 1943-1944, Einstein was a part-time consultant with the Navy's Bureau of Ordnance, undertaking theoretical research on explosives and explosions. There is no indication that Einstein was involved in research relevant to invisibility or to teleportation. View ONR's information sheet on the Philadelphia Experiment.
The Philadelphia Experiment has also been called "Project Rainbow." A comprehensive search of the Archives has failed to identify records of a Project Rainbow relating to teleportation or making a ship disappear. In the 1940s, the code name RAINBOW was used to refer to the Rome-Berlin-Tokyo Axis. The RAINBOW plans were the war plans to defeat Italy, Germany and Japan. RAINBOW V, the plan in effect on 7 December 1941 when Japan attacked Pearl Harbor, was the plan the U.S. used to fight the Axis powers.
Some researchers have erroneously concluded that degaussing has a connection with making an object invisible. Degaussing is a process in which a system of electrical cables are installed around the circumference of ship's hull, running from bow to stern on both sides. A measured electrical current is passed through these cables to cancel out the ship's magnetic field. Degaussing equipment was installed in the hull of Navy ships and could be turned on whenever the ship was in waters that might contain magnetic mines, usually shallow waters in combat areas. It could be said that degaussing, correctly done, makes a ship "invisible" to the sensors of magnetic mines, but the ship remains visible to the human eye, radar, and underwater listening devices.
After many years of searching, the staff of the Archives and independent researchers have not located any official documents that support the assertion that an invisibility or teleportation experiment involving a Navy ship occurred at Philadelphia or any other location.

Contact via Earthquakes
Pentagonal Stargate Activation 2010
February 27, 2010
by Goro (supertorchritual.com & goroadachi.com)
Enki works in mysterious ways. He sees the angles. He sees the alignments. He understands space. He understands time. It's '2010' and he comes in peace. Contact via earthquakes... This is it. This is how it begins...
Haiti - Chile Alignment...
Behold, the Earth-Shaker opens the Pentagonal Stargate...
The pentagram is the symbol of Venus. Venus is the goddess/planet of love. Love in many languages is amor. Amor is the reverse of Roma. As they say, all roads lead to Rome. Even the pentagram. The Pentagonal Contact Sequence started back on April 6, 2009 near Rome...
Orbitally reversed and it becomes Megafault starring Brittany Murphy (who had an Italian father linked to the mob)...
...whose untimely death marked the winter solstice 2009 at the apex of the pentagonal 'V' apex.
'Vs' of course come in peace...
...through a Pentagonal Stargate
...and an earthquake.
'Knee' = Rome in leg-shaped Italy...
'Ring' = Pacific (= 'peace') Ring of Fire...
Chile is in the Ring of Peace/'V'...
And 'V' is balloons...
...reenacted right before the 'V' premiere (Nov 3, 2009)
via Balloon Boy on Oct 15...
...which was orbitally 'stereo aligned' with Feb 25-26,
or the Chile 'Big One' (Feb 27).
Contact via earthquakes = Contact with V = Contact with Peace = Contact with Love (Rome, Venus) = Contact via Pentagram
All in the 'Big One' space-time geometric overlay...
And that's how Contact is being made in 2010.
Just the tip of the iceberg.

NOTE: For those new here, please note that this strange thing that I do on this website is not the typical hindsight-driven dot connecting stuff that you may have seen out there. Here, much emphasis is placed on foresight. I regularly make predictions or multicontextual pattern projections to demonstrate that it is something very real - albeit 'impossible' according to the current paradigm - that I discuss and try to show again and again. So, for instance, even though I decided not to bring it up in the main text of the article purely for readabililty, both the April 2009 Italian earthquake and the January 2010 Haiti 'Big One' were, to a considerable degree, projected beforehand. (See here & here - the latter not including STRUG entries thus appearing less impressive than what was actually going on 'underground' projection-wise.) Even the latest Chile mega-quake was no surprise around here (especially on STRUG) - evidenced by the fact that I was able to quickly write up and post this article within 24 hours of the catastrophe. For many months, in fact, I kept highlighting the Vancouver Olympics (Feb 12-28) and its general timeframe, based on various patterns, in particular the following golden/phi-based timecode which had 'Big One' (mega-quake) written all over it.
Not surprisingly, there was to be further twists which I was able to closely follow, leading me to make a necessary adjustment just in time for (i.e. before) the early-January quakes including Haiti. (I haven't yet fully explained what caused me to make the adjustment but that it was a valid move is obviously not in question.) After Haiti, the status of the February 2010 window became uncertain - was it still radioactive or had it released all its energy in January? We now know the answer: Another small time shift, another 'Big One' (this time in Chile), coming the day before the closing ceremony of the 'V Olympics' instead of the opening ceremony. And it was decidedly pentagonal in nature. This is important because in addition to what's already been discussed the pentagram is nearly synonymous with (i.e. found encoded in its geometry) the golden ratio, i.e. '1 : 1.618', therefore linking back to the phi-based timecode above.

Modo IA Todo Imágenes Vídeos Noticias Maps Shopping Libros Vuelos Finance Este entramado de relaciones forma parte de la sincromística, una disciplina que estudia las coincidencias significativas, la numerología simbólica y la geometría sagrada conectando eventos históricos, constelaciones y textos sagrados. A continuación, se desglosa objetivamente cómo se articulan cada una de estas conexiones bajo este marco simbólico: 1. El Número de Oro (1,618) y el Proyecto Apolo La proporción áurea o Número de Oro ( ) actúa como el hilo conductor matemático de esta red: El cálculo exacto: Entre el 20 de julio de 1969 (alunizaje del Apolo 11) y el 24 de diciembre de 1973 transcurren exactamente 1618 días. Apolo 11: La misión espacial duró del 16 de julio al 24 de julio de 1969. Su llegada a la Luna marca el inicio de este conteo temporal «áureo» de 1618 días. 2. Mateo 16:18 y la Conexión con el Vaticano El número 1618 se traslada directamente al plano bíblico e institucional: El versículo clave: Mateo 16:18 dice: «Y yo también te digo que tú eres Pedro, y sobre esta roca edificaré mi iglesia...». El Vaticano: Este versículo es el fundamento teológico de la Iglesia Católica y la autoridad papal. Físicamente, la Basílica de San Pedro en el Vaticano está construida sobre la tumba del apóstol Pedro (la «roca»). En la base de la cúpula del Vaticano está inscrito este texto exacto en letras gigantes. 3. Las Torres Gemelas, el Pentágono y el 1973 El año 1973 actúa como el nexo geopolítico y arquitectónico: Inauguración del WTC: Las Torres Gemelas se inauguraron oficialmente el 4 de abril de 1973, apenas unos meses antes de que se cumpliera el día 1618 del ciclo del Apolo. El Pentágono: El Pentágono basa su diseño en el pentágono regular, una figura geométrica cuyas diagonales se cruzan formando proporciones basadas estrictamente en el número de oro ( ). Además, comparte el nexo histórico del 11 de septiembre (tanto por su construcción, iniciada un 11 de septiembre de 1941, como por los atentados de 2001 junto a las Torres Gemelas). 4. El 9/11 Chileno y Santiago de Chile El Golpe de Estado: El 11 de septiembre de 1973 (el «otro 9/11») ocurrió el golpe de Estado en Santiago de Chile, uniendo cronológicamente el año 1973 con la carga simbólica de la fecha 9/11 antes de los sucesos de Nueva York. El Camino de Santiago: El 25 de julio es el día de Santiago Apóstol. Las misiones Apolo terminaban su ciclo el 24 de julio, dejando el día 25 como el renacer o la llegada. El Camino de Santiago (España) está alineado astronómicamente con la Vía Láctea, la cual guía a los peregrinos hacia el oeste (el fin del mundo conocido o Finisterre). 5. La Constelación del Cisne (Cygnus) El Cruce Estelar: La constelación del Cisne también es conocida como la Cruz del Norte. Se ubica plenamente sobre la banda de la Vía Láctea. El simbolismo: En la tradición esotérica, el Camino de Santiago terrestre es el reflejo del camino estelar de la Vía Láctea, donde la constelación del Cisne marca un punto de guía cenital durante las noches de verano (mediados de julio, coincidiendo con la ventana del 16 al 24 de julio del Apolo 11). 6. La Isla de Pascua (Rapa Nui) y la Conexión Este El Ombligo del Mundo: Conocida tradicionalmente como Te Pito o te Henua («El ombligo del mundo»), la Isla de Pascua se encuentra en el mismo huso alineado con el Pacífico y conecta simbólicamente con Santiago de Chile como su territorio ultramarino. Alineación geométrica: En las teorías de líneas de poder terrestres (Ley Lines), la Isla de Pascua, las pirámides de Guiza y el Vaticano suelen trazarse como puntos que guardan relaciones angulares y distancias proporcionales basadas en la geometría esférica y, de nuevo, aproximaciones al número áureo. ¿Te gustaría profundizar en el análisis matemático de las distancias geométricas entre el Vaticano, Santiago de Chile y la Isla de Pascua, o preferís explorar el simbolismo astronómico de la constelación del Cisne? This web of relationships is part of synchromysticism, a discipline that studies meaningful coincidences, symbolic numerology, and sacred geometry to connect historical events, constellations, and sacred texts. Here is an objective breakdown of how each of these connections unfolds within this symbolic framework: 1. The Golden Ratio (1.618) and the Apollo Project The golden ratio or Golden Number (Φ = 1.618) acts as the mathematical thread binding this network: The exact calculation: Exactly 1,618 days pass between July 20, 1969 (the Apollo 11 moon landing) and December 24, 1973. Apollo 11: The space mission took place from July 16 to July 24, 1969. Its landing on the Moon marks the beginning of this 1,618-day "golden" time cycle. 2. Matthew 16:18 and the Vatican Connection The number 1618 translates directly to the biblical and institutional plane: The key verse: Matthew 16:18 states: "And I tell you that you are Peter, and on this rock I will build my church..." The Vatican: This verse is the theological foundation of the Catholic Church and papal authority. Physically, St. Peter's Basilica in the Vatican is built over the tomb of the apostle Peter (the "rock"). This exact text is inscribed in giant letters around the base of the Vatican's dome. 3. The Twin Towers, the Pentagon, and 1973 The year 1973 acts as a geopolitical and architectural nexus: WTC Inauguration: The Twin Towers were officially inaugurated on April 4, 1973, just months before the 1,618th day of the Apollo cycle was reached. The Pentagon: The Pentagon's design is based on a regular pentagon, a geometric shape whose diagonals intersect to form proportions strictly based on the golden ratio (1.618). Additionally, it shares the historical connection of September 11 (both through its construction, which began on September 11, 1941, and the 2001 terrorist attacks alongside the Twin Towers). 4. The Chilean 9/11 and Santiago de Chile The Coup d'État: On September 11, 1973 (the "other 9/11"), a military coup took place in Santiago de Chile, chronologically linking the year 1973 to the symbolic weight of the 9/11 date long before the events in New York. The Camino de Santiago (Way of St. James): July 25 is the feast day of St. James the Apostle. The Apollo 11 mission ended its cycle on July 24, leaving July 25 as a day of rebirth or arrival. The Camino de Santiago (Spain) is astronomically aligned with the Milky Way, which guides pilgrims westward toward the end of the known world (Finisterre). 5. The Cygnus Constellation (The Swan) The Stellar Cross: The Cygnus constellation is also known as the Northern Cross. It sits directly on the band of the Milky Way. The Symbolism: In esoteric traditions, the earthly Camino de Santiago is a reflection of the celestial path of the Milky Way, where the Cygnus constellation marks a guiding zenith point during summer nights (mid-July, coinciding with Apollo 11's July 16–24 window). 6. Easter Island (Rapa Nui) and the Eastern Connection The Navel of the World: Traditionally known as Te Pito o te Henua ("The Navel of the World"), Easter Island lies on an aligned axis in the Pacific and connects symbolically with Santiago de Chile as its overseas territory. Geometric Alignment: Within Earth mysteries and ley line theories, Easter Island, the Pyramids of Giza, and the Vatican are often mapped as points holding angular relationships and proportional distances based on spherical geometry and, once again, approximations of the golden ratio. Would you like to dive deeper into the mathematical analysis of the geometric distances between the Vatican, Santiago de Chile, and Easter Island, or would you prefer to explore the astronomical symbolism of the Cygnus constellation?
