Question

When the frequency of an electromagnetic wave increases, its energy
A. increases.
B. decreases.
C. stays the same.
D. It depends on the exact type of electromagnetic wave.

Answer 1

When the frequency of an electromagnetic wave increases, its energy also must increase. As this occurs, its speed, wavelength, and amplitude all decreases. So, the correct choice would be A. Increases. 

I hope I was able to satisfyingly answer your question. :) 

Answer 2

At the time when the frequency of an electromagnetic wave increases, its energy increased.

The following information should be considered:

• When the electromagnetic wave increases so the energy should be increased.
• Due to all this, the speed, wavelength all should be decreased.

Therefore we can conclude that At the time when the frequency of an electromagnetic wave increases, its energy increased.
