Question

as the frequency of an electromagnetic wave increases, the amount of energy in that wave... stays the same. increases. decreases.

Explanation:

The energy of an electromagnetic wave is directly proportional to its frequency. The formula for the energy of a photon (a quantum of electromagnetic radiation) is \(E = h
u\), where \(E\) is energy, \(h\) is Planck's constant (\(h = 6.626\times10^{-34}\space J\cdot s\)), and \(
u\) is the frequency of the wave. Since \(h\) is a constant, when \(
u\) (frequency) increases, \(E\) (energy) must increase as well.

Answer:

B. increases.
