Question

which best describes the energy of a sound wave as it travels through a medium? it increases. it decreases. it remains the same. it depends on the medium.

Explanation:

As a sound wave travels through a medium, it loses energy due to factors like friction and absorption. This causes the amplitude of the wave (which is related to its energy) to decrease over time. For example, a loud sound becomes quieter as it moves away from the source, indicating a loss of energy.

Answer:

It decreases.
