Question

as the frequency of a wave increases on the electromagnetic spectrum, what happens to the waves energy?
a. the waves energy does not depend on its frequency.
b. it stays the same.
c. it increases.
d. it decreases.

Explanation:

The energy of a wave in the electromagnetic spectrum is given by the formula \(E = h
u\), where \(h\) is Planck's constant (\(h> 0\)) and \(
u\) is the frequency of the wave. Since \(h\) is a positive constant, when the frequency \(
u\) increases, the energy \(E\) (which is the product of \(h\) and \(
u\)) also increases.

Answer:

C. It increases.
