User Guide
Calculate the frequency of an electromagnetic wave by entering a value for the corresponding energy per photon for the em wave.
Electromagnetic waves are divided up into regions of what is called the electromagnetic spectrum. Starting with the highest frequencies, the spectrum is made up of gamma rays, x rays, ultraviolet, visible light, infra-red, microwave, and radio waves. This energy per photon to frequency calculator can be used for all types of waves in the electromagnetic spectrum.
Enter the energy value per photon, along with selecting the relevant energy measurement units, and then select the required frequency measurement units to calculate the corresponding em wave frequency. The result will then be displayed in the answer box along with a dynamic conversion scale to show how frequency varies for different photon energies, above and below the entered value.
Formula
The formula used to calculate the frequency of an electromagnetic wave is:
f = E / h
Symbols
- f = Frequency of EM wave
- E = Photon energy
- h = Planck constant
Photon Energy
Enter the energy per photon for the electromagnetic wave. 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.
Frequency
This is the number of completed cycles of oscillation per unit of time, a photon generates as an electromagnetic wave, as it propagates through a medium at the speed of light.
