Question

Two vibrating tuning forks produce progressive waves given by y₁ = 4sin (500πt) andy₂ = 2sin (506πt). These tuning forks are held near the ear of a perseon. The person will hear :-

Options

A.3 beats/s with intensity ratio between maxima and minima equal to 2

B.3 beats/s with intensity ratio between maxima and minima equal to 9

C.6 beats/s with intensity ratio between maxima and minima equal to 2

D.6 beats/s with intensity ratio between maxima and minima equal to 9

Solution

n₁ = 250 Hz n₂ = 253 Hz
Beats n₂ - n₁ = 3 Hz
= 9
