Question

Sound is a type of mechanical wave and must have a medium through which to travel. Sound will move at different speeds when which of the following occurs?

A. The sound is fully absorbed in an object.

B. The sound moves from air to water.

C. The sound pitch increases.

D. The sound is reflected off a surface.

Answer 1

Hey there!

The answer would be B. The sound moves from air to water.

Sound travels through different mediums. It goes fastest in solids, a little slower in liquids, and slowest in air. Sound is a very fast wave, but remember that mediums can differ that. In a vacuum space, there is no sound at all. (ex. outer space)

Hope this helps !
