Two tuning forks have frequencies 380 and 384 Hz respectively. When they are sounded together they
produce 4 beats. After hearing the maximum sound how long will it take to hear the minimum sound

A

`1//2sec`

B

`1//4sec`

C

`1//8sec`

D

`1//16`sec

Text Solution

Verified by Experts

The correct Answer is:
C
beat period `T=(1)/(n_1-n_2)=(1)/(384-380)xx(1)/(4)`sec, Hence minimum time interval between and minima `t=(T)/(2)=(1)/(8)sec`
