Compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have

High energy and Low wavelength.

Explanation: We are given an electromagnetic wave having high energy, so by using Planck's equation:

where, E = energy

h = Planck's constant

= frequency

here, Energy and frequency follow direct relation and hence high frequency means high energy.

and

= Frequency

c = speed of light

= wavelength

Here, the frequency is inversely related to the wavelength, hence high frequency means low frequency.
