Question 5

Why does a wave's speed change when it moves from one medium to another with a different density?

Accepted Answer

The density of the new medium affects the forces between molecules, which changes the wave's speed.

Answer

The wavelength of the wave changes when it enters the new medium, but this does not affect its speed.

Answer

The frequency of the wave does not change when it enters the new medium, so this cannot explain the change in speed.

Answer

The temperature of the new medium can affect the wave's speed, but this is not the primary reason for the change.
