Question

The medium through which a mechanical wave passes can be a solid, liquid, or gas. Properties of a wave change when it moves from one medium to another. What happens to the speed of a wave when it moves

from a gas to a solid?
A It speeds up.
B. It shows down
c. It remains the same
Dit speeds up and then slows down.

Help pls hurry!!!

Answer 1

Option A

Step-by-step explanation:

Mechanical waves requires some medium to travel through. They travel faster in the dense medium as compared to a free medium.

The speed of a mechanical wave is fastest in the solid medium and the slowest in the gaseous medium. Hence, as the wave traverses from gaseous medium to the solid medium, its speed increases.

Thus, option A is correct
