The lengths of two closed organ pipes are 0.750 m an 0.770 m. If they are sounded together, 3 beats per second are produced. The velocity of sound will be:
Text Solution
Verified by ExpertsThe correct answer is:
C
For first closed organ pipe
n 1 = 
= 
For second closed organ pipe
n 2 = 
= 
But n 1 – n 2 = 3
– 
= 3
– 
= 3
v 
= 3
⇒ v = 
= 346.5 m/sec
