How does the frequency of light change as wavelength increases?

Answer 1

Owen Atkinson

The frequency of light is inversely proportional to the wavelenght.

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

#c=f lambda#

Where #c# is the speed of light.

Thus, in relation to wavelength:

#f = c/lambda#

Thus, frequency decreases with increasing wavelength.

It decreases in proportion.

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 3

Levi Anderson

The frequency of light is inversely proportional to its wavelength. This means that as the wavelength of light increases, its frequency decreases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
