Question
Two vibrating tuning forks produce progressive waves given by y1 = 4 sin 500πt and y2 = 2 sin 506 πt. Number of beats produced per minute is : -
Options
A.3
B.360
C.180
D.60
Solution
f1 = 
= 250 ; f2 = 
= 253
∴ ᐃf = 3 s-1 = 3 × 60 min-1 = 180 min-1.
= 250 ; f2 = = 253∴ ᐃf = 3 s-1 = 3 × 60 min-1 = 180 min-1.
