The relationship light waves is no different than any other wave; the product of the wavelength and frequency is equal to the speed of the wave.

#### Explanation:

Let $\lambda =$ the wavelength of any wave.
Let $f =$ the frequency of that wave.
Let $v =$ the speed of that wave.

The relationship between these three is:

$v = \lambda f$

For light, we have special symbol, C, that we use to represent its speed. Therefore, for light, the equation becomes:

$C = \lambda f$
