Sound waves are passing through two routes-one in straight path and the other along a semicircular path of radius 
and are again combined into one pipe and superposed as shown in the figure. If the velocity of sound waves in the pipe is 
, then frequencies of resultant waves of maximum amplitude will be multiples integral of
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Path difference 
where, 
frequency
So, multiple integral
