User Guide

Calculate the wavelength of an electromagnetic wave in a vacuum by entering a value for the corresponding  frequency.

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 frequency to wavelength calculator can be used for all types of waves in the electromagnetic spectrum.

Enter the frequency value, along with selecting the relevant frequency measurement units, and then select the required wavelength measurement units to calculate the corresponding wavelength. The result will then be displayed in the answer box along with a dynamic conversion scale to show how wavelength varies for different frequencies, above and below the entered value.

Formula

The formula used to calculate the wavelength of electromagnetic waves in a vacuum is:

λ = c₀ / f

Symbols

• λ = Wavelength of EM wave
• c₀ = Speed of light in a vacuum
• f = Frequency of EM wave

Frequency

Enter the frequency of the electromagnetic wave in a vacuum.  This is the number of completed cycles of oscillation per unit of time, a photon generates as a electromagnetic wave, as it propagates through a vacuum at the speed of light.

Wavelength

This is the distance of one complete cycle of oscillation, for an electromagnetic wave, produced by a photon propagating through a vacuum.
