Question

What is the relationship between frequency and wavelength in electromagnetic radiation?

Answer 1

Frequency and wavelength are inversely proportional.

Explanation:

Frequency and wavelength are inversely proportional.

`c=f·lambda` `("The speed of light is directly proportional to"` `f` and `lambda)`.

`c/f=lamda` `("The speed of light is directly proportional to"` `f`, and `f` is inversely proportional to `lambda)`.

`c/lambda=f` `("The speed of light is directly proportional to"` `lambda`, and `lambda` is inversely proportional to `f`.

Notice in the diagram below that as wavelength decreases, the frequency increases. The speed of light, `c` is a constant, so when wavelength decreases, frequency increases and vice versa.
