Which property of electromagnetic waves must go down as the frequency goes

up?

Wavelength

Explanation:

Velocity of a wave is given by

where

= Frequency of wave =

= Wavelength of wave

We have the relation

Now, velocity of the wave in a given medium remains constant. So, if the frequency increases the wavelength must decrease in order to keep the velocity of the wave constant. Also if the frequency decreases the the wavelength increases.
