To calculate wavelength, use the formula wavelength = speed divided by frequency. The calculator will calculate the wavelengths given the frequencies. This is also the frequency used by wifi! Do you have an energy transition between two states and wonder what wavelength of light this corresponds to? The result will be the energy the photon is carrying. Physicist David Mermin proposed a new measurement unit, the "light nanosecond", jokingly called phoot: a portmanteau of photos, light in Latin, and foot. 2006 - 2023 CalculatorSoup This equation can also be used to determine the maximum wavelength of light necessary to ionize metals. This is the energy possessed by a single photon, oscillating at the specified wave frequency, as it propagates through a medium at the speed of light. Every moving particle with specific kinetic energy behaves like a wave and can be described as having a specific wavelength. If you know the frequency of a wave traveling through a medium you can calculate how far it is between each crest of the wave or each trough of the wave. This is the distance of one complete cycle of oscillation, for an electromagnetic wave, produced by a photon propagating through a vacuum. Wavenumber/Wavelength Converter.
