Question

With the help of diagram, show the difference between a high pitch and low pitch sound.

Answer 1

Answer AND Explanation:

The frequency of a sound wave is what your ear understands as pitch. A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch. In Figure 10.2 sound A has a higher pitch than sound B. For instance, the chirp of a bird would have a high pitch, but the roar of a lion would have a low pitch.
