2

Can energy be lost?
A
No. energy is rather ‘converted’ rather than lost.
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
Q
Can a sound wave travel through empty space?
A
No, as there is nothing for sound to travel through.
