Which is the correct formula for finding the frequency of an electromagnetic wave? f = c – f = f = + c f =

f = c / λ

Explanation:
Electromagnetic waves are types of periodic waves. They propagate with the same speed as light (3 * 10⁸ m/sec).
Therefore:
velocity of wave = c

Now, the equation that relates speed of wave and its frequency is as follows:
c = λf
where:
c is the speed of wave
f is the frequency of the wave
λ is the wavelength of the wave

Solve the above equation for frequency, we will end up with:
f = c / λ

Hope this helps :)

The answer is going to be c

Ibelieve the correct answer would be c.
