Question

wave y and wave z are two types of electromagnetic waves traveling through a vacuum. suppose the frequency of wave y is about three times greater than the frequency of wave z. which best compares the energy transferred by the two waves? it is the same for each wave because the amount of energy transferred is constant in all types of electromagnetic waves. wave y transfers about one - third the amount of energy as wave z because energy and frequency have an inverse relationship. wave y transfers about three times the amount of energy as wave z because energy and frequency have a direct relationship. it is zero for each wave because when waves travel through a vacuum, they do not transfer energy.

Explanation:

Step1: Recall energy - frequency relation

The energy $E$ of an electromagnetic wave is given by $E = h
u$, where $h$ is Planck's constant and $
u$ is frequency. Energy and frequency are directly proportional.

Step2: Analyze given frequencies

Since frequency of wave Y is three - times that of wave Z, and $E\propto
u$, wave Y has three - times the energy of wave Z.

Answer:

Wave Y transfers about three times the amount of energy as wave Z because energy and frequency have a direct relationship.
