Three sound sources `A`, `B` and `C` have frequencies `400`, `401` and `402 H_(Z)`, respectively. Cacluated the number of beats noted per second.

A

0

B

1

C

2

D

3

Text Solution

Verified by Experts

The correct Answer is:
C
The no. of beats heard per second will be equal to the maximum frequency difference of the sources if frequencies of the sources vary with equal value gaps
So maximum no. of beats heard per second=402-400=2
