Three sound waves of equal amplitudes have frequencies `(v - 1), v, (v + 1)`. They superpose to give beats. The number of beats produced per second will be :

A

n

B

`n//2`

C

2

D

1

Text Solution

Verified by Experts

The correct Answer is:
D
Beat frequency is the difference between the successive frequencies i.e. `(n + 1) - n = 1`
