Question 20
F

A loudspeaker is placed next to a candle flame.

When the loudspeaker plays a loud note, the flame flickers backwards and forwards. The flame is not blown away from the loudspeaker.

What does this show about the sound wave?

[1]
A

The air vibrates about a fixed position while the wave travels outwards

B

The air moves away from the loudspeaker and carries the sound with it

C

The sound wave is transverse because the flame moves from side to side

D

The sound wave transfers no energy because the flame is not blown away
