What is the relationship between frequency and wavelength?

Frequency and wavelength are not related.

As the frequency increases, the wavelength decreases.

Frequency and wavelength are opposites of each other

As the frequency increases, the wavelength increases.

The correct relationship between frequency and wavelength is that as the frequency increases, the wavelength decreases. This is because frequency is the number of complete cycles of a wave that pass a given point in a certain amount of time, while wavelength is the distance between two corresponding points on a wave. Therefore, as the frequency increases, there are more wave cycles passing a point in the same amount of time, leading to a shorter distance between each cycle (i.e. a shorter wavelength).
