As the frequency of a wave on the electromagnetic spectrum decreases, what happens to the wave's energy?
O A. It increases:
B. The wave's energy does not depend on its frequency.
C. It stays the same.
O D. It decreases.

D. It decreases.

Explanation:

As the frequency of a wave on the electromagnetic spectrum decreases the energy of the wave also decreases.

Wave energy and frequency are directly proportional to one another.

  Energy of an electromagnetic wave is given as:

  Energy  = h f

  where h is the plank's constant

              f is the frequency

We see that energy is proportional to frequency. As you go down the electromagnetic spectrum, the amount of wave energy begins to diminish.
