Two vibrating tuning forks produce progressive waves given by Y1=4sin500(pi)t and Y2= 2sin506(pi)t. No. of beats produced per minute is
a) 360
b) 60
c) 180
d) 3
Deepali, the beats are the diffrence in frequencies of two vibrating folks .as from eqn y1 frequency is 250 and from eqn y2 frequency is 253 as diffrence is 3 so answer is 3
