Question

When a mechanical wave travels through a given medium, it loses energy to the medium.

• A. True
• B. False

Answer 1

The correct option is A

True

A mechanical wave travels through an elastic medium by means of vibrations of molecules around their mean position. Through vibrations, these molecules transfer their energy to the next set of molecules and so on. At the same time, there will be a loss of energy to the surrounding in terms of heat energy.
