Total: 60

Sound waves are passing through two routes-one in straight path and the other along a semicircular path of radius rand are again combined into one pipe and superposed as shown in the figure. If the velocity of sound waves in the pipeis v, then frequencies of resultant waves of maximum amplitude will be integral multiples of

v
r(π−2)
