Which describes the relationship between a wave’s amplitude and its energy?

Question

Larger amplitudes contain more energy.
Smaller amplitudes contain more energy.
Amplitudes that increase over time contain less energy.
Amplitudes that decrease over time contain more energy.

Answer 1

The correct statement is: Larger amplitudes contain more energy.

In general, for mechanical waves, the energy carried by the wave is proportional to the square of the amplitude. This means that as the amplitude increases, the energy of the wave increases as well.
