3
Q

How are sound wave created?

A

Through many vibrations in the air.

4
Q

What is the wave speed equation?

A
V = F x A
where
V = The wave speed in m/s
F = The frequency in hertz.
A = The wavelength in meters.
5
Q

What are transverse waves?

A

A wave where vibrations are at right angles.q

6
Q

What are longitudinal waves?

A

The vibrations follow the same direction as the direction.

7
Q

What is compression (air)?

A

A region of close air particles.

8
Q

What is refraction (air)

A

A region of distant air particles.

9
