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"#?
