A source S having frequency 600 Hz is kept at rest at bottom of a flowing river. Find out the frequency detected by a stationary detector present above the river in air. [Velocity of sound in water = 1500 m/s; velocity of sound in air = 300 m/s]
Text Solution
Verified by ExpertsThe correct answer is:
B
The frequency is a characteristic of source. It is independent of the medium.
