Final answer:

The energy of a sound wave remains constant as it travels through a medium, influenced by factors like amplitude and medium properties.


Explanation:

The energy of a sound wave remains the same as it travels through a medium. Sound waves carry energy through variations in pressure and particle motion, but this energy is conserved during propagation. For example, when sound travels through air, the energy it carries does not increase or decrease.

Sound waves travel at different speeds in different mediums, such as air and water, but the energy carried by the sound wave itself remains constant within the medium.

Amplitude and energy are related in waves; with sound waves, as the amplitude decreases with distance, the energy spreads out but overall remains the same.
