Question
Two sources of sound placed close to each other, are emitting progressive waves given by
y1 = 4 sin 600 πt and y2 = 5 sin 608 πt. An observer located near these two sources of sound will hear:
y1 = 4 sin 600 πt and y2 = 5 sin 608 πt. An observer located near these two sources of sound will hear:
Options
A.4 beats per second with intensity ratio 81 : 1 between waxing and waning
B.4 beats per second with intensity ratio 25 : 16 between waxing and waning
C.8 beats per second with intensity ratio 25 : 16 between waxing and waning
D.8 beats per second with intensity ratio 81 : 1 between waxing and waning
Solution
Beat frequency = 304 – 300 = 4 Hz.
