Answer:
D. It decreases.
Step-by-step 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.
- Frequency is the number of waves that passes through a point per unit of time.
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.
