Which of the following statements correctly explains the relationship between FM and AM radio waves?

A.
FM radio waves carry less energy than AM radio waves. This is supported by the fact that FM radio waves have a shorter wavelength compared to AM radio waves.

B.
FM radio waves carry less energy than AM radio waves. This is supported by the fact that FM radio waves have a longer wavelength compared to AM radio waves.

C.
FM radio waves carry more energy than AM radio waves. This is supported by the fact that FM radio waves have a shorter wavelength compared to AM radio waves.

D.
FM radio waves carry more energy than AM radio waves. This is supported by the fact that FM radio waves have a longer wavelength compared to AM radio waves.

Answer 1

The correct answer is:

C. FM radio waves carry more energy than AM radio waves. This is supported by the fact that FM radio waves have a shorter wavelength compared to AM radio waves.

In the electromagnetic spectrum, energy is inversely related to wavelength; shorter wavelengths correspond to higher energy. Therefore, since FM radio waves have a shorter wavelength than AM radio waves, they carry more energy.
