Just a simple equation would do the job well.

Explanation:

The wavelength of a wave is given by:

lambda=v/f

where:

  • v is the velocity of the wave in meters per second

  • f is the frequency of the wave in hertz

In the case of electromagnetic radiation, the energy is spread out at the speed of light, c, so the equation becomes:

lambda=c/f

Now, you can apply this equation to some "EM" wavelength problems. What is the wavelength of an electromagnetic wave that has a frequency of 1 \ "Hz"?
