The diagram represents two different sound waves.

A

The frequency and pitch of X is less then that of Y of X is less than Y.

B

The frequency and pitch of X is same as the frequency and pitch of Y.

C

The frequency of X is less than Y but its pitch is same as Y.

D

The frequency of X is same as Y but its pitch is higher than Y.

Text Solution

Verified by Experts

The correct Answer is:
A
The frequency of wave X is lower than wave Y, hence its pitch is lower than wave Y too. The pitch of sound depends on the frequency.
