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

#3.f=c/lambda#
