Question

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)/(2)s`
B. `(1)/(4)s`
C. `(1)/(8)s`
D. `(1)/(16)s`

Answer 1

Correct Answer - C
Time for one beat `= (1)/(4) s`
Time between maximum and minimum is
`= ((1//4))/(2) = (1)/(8) s`
