Questions
Two vibrating tuning forks produce progressive waves given by Number of beats produced per minute is
detailed solution
Correct option is B
From the given equations of progressive waves ω1=500π and ω2=506π ∴ n1=250 and n2=253 So beat frequency=n2−n1=253−250=3 beats per sec ∴ Number of beats per min = 180.Talk to our academic expert!
