Two vibrating tuning fork produce progressive waves given by `y_(1) = 4 sin 500 pi t` and `y_(2) = 2 sin 506 pi t`. Number of beats produced per minute is :-

A

3

B

360

C

180

D

60

Text Solution

Verified by Experts

The correct Answer is:
C
Number of beats per second `=n_(2)-n_(1)=3 `
`( :' n_(1)=250 , n_(2)=253)`
`implies ` Number of beats produced per minute
`=3xx60=180`
