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
Beats n2 - n1 = 3 Hz
= 9Create a free account to view solution
