Two waves ` y=0.25 sin 316 t` and `y=0.25 sin 310 t` are travelling in same direction. The number of beats produced per second will be

A

6

B

`3//pi`

C

`3

D

`3pi`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(1) = (316)/(2pi), n_(2) = (310)/(2pi)`
`n = n_(1) - n_(2) = (316)/(2pi) - (310)/(2pi) = (6)/(2pi) = (3)/(pi)`
