Two sound waves, A and B, are produced by loudspeakers. The amplitude and frequency of each wave are given in the table:
| Sound | Amplitude (mm) | Frequency (Hz) |
|---|---|---|
| A | 1.5 | 320 |
| B | 0.8 | 640 |
How does sound B compare with sound A?
B is louder and has a higher pitch.
B is louder and has a lower pitch.
B is quieter and has a higher pitch.
