Well you use an equation for that...

#### Explanation:

Frequency of a wave is given by the equations:

- #1.f=1/T#

where:

- #f#is the frequency of the wave in hertz
- #T#is the period of the wave in seconds

- #2.f=v/lambda#

where:

- #f#is the frequency of the wave in hertz
- #v#is the velocity of the wave in meters per second
- #lambda#is the wavelength of the wave in meters

For electromagnetic waves, they all travel at the speed of light, and so their velocity becomes#c#. Thus, we make a third equation, which is:

- #3.f=c/lambda#Answer link
