What happens when a sound wave moves from water to air?


It slows down.

It speeds up.

It stays the same.

It reverses.


When two mechanical waves have a displacement in opposite directions, and they overlap, what will the resulting wave look like and why?


The new wave will have the same displacement as the original waves due to constructive interference.

The new wave will have a smaller displacement than either of the original waves due to destructive interference.

The new wave will have a greater displacement than either of the original waves due to constructive interference.

The new wave will have the same displacement as the original waves due to destructive interference.

Question 1

The correct answer for above statement is:

It speeds up.

Explanation;

In the air, the sound emanating from water will slow down. The sound goes by the vibration of the molecules and particles existing in the medium. The water is compact medium and the molecules present in water are closely bound as contrasted to the air.Sound waves travel FASTER within water than through air.

Question 2.

The correct answer is;

The new wave will have the same displacement as the original waves due to constructive interference.

Explanation:

The wave interference is supposed to be a constructive wave interference if the top of a wave meets the crest of another wave of the equal frequency at the identical point.Constructive wave interference is a wave interference which happens when in phase waves appears with each other and forms a new wave with larger amplitude.
