Question

How does the frequency of light change as wavelength increases?

Answer 1

It decreases in proportion.

Explanation:

Assuming the light travels in the same medium, its speed remains constant and so to satisfy the equation `c=flambda`,if `lambda` increases, then `f` must decrease.

Answer 2

The frequency of light is inversely proportional to the wavelenght.

Explanation:

The frequency `f` and the wavelength `lambda` of light are related by the equation.

`c=f lambda`

Where `c` is the speed of light.

So, in terms of wavelength:

`f = c/lambda`

So, as wavelength increases, frequency deceases.
