Answer 2

Sound

High pitch or low pitch of the sound is decided according to the frequency of the vibration of the sound waves. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.

In the given figure,

1st graph has low frequency wave and 2nd graph has high frequency wave. So, Wave (a) will be of low pitch and 2nd graph that is Wave (b) is of high pitch.
