What equation shows how velocity is related to frequency and wavelength?

Propagation velocity of a wave is propotional to the product the wave's frequency (f) and wavelength (lambda):

The correct answer is .

Explanation:

The expression of the wavelength in terms of the frequency is as follows;

Here, c is the speed of the light, f is the frequency of the wave and is the wavelength of the wave.

The wavelength and the frequency has an inverse relationship between them.

If the frequency of the wave increases then the wavelength of the wave decreases.

If the frequency of the wave decreases then the wavelength of the wave increases.

c. 75.7

i think that is the right

your answer would be “dry”
