Question

Which describes how to compare the energy of two different waves?

A. measure their frequencies

B. measure their periods

C. measure their amplitudes

D. measure their wavelengths

Answer 1

C measures their amplitudes. Hope this helps! :)

Answer 2

Answer;

C. measure their amplitudes

Explanation;

• The amount of energy in a wave is related to its amplitude and its frequency.
• The amplitude of a wave is how the wave is measured from the rest position or mid-line to the top of a crest or bottom of a trough, measured in meters.
• A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave. For instance in the case of sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet.
