Questions
A vehicle with a horn of frequency n is moving with a velocity of 30 m/s in a direction perpendicular to the straight line joining the observer and the vehicle. The observer perceives the sound to have a frequency when he is at the shortest distance between them. Then (if the sound velocity in air is 300 m/s)
detailed solution
Correct option is B
No shift in frequency as there is zero relative velocity at the given instant.Talk to our academic expert!

A source of sound having natural frequency f0 = 1800 Hz is moving uniformly along a line separated from a stationary listener by a distance l = 250 m. The velocity of source is n = 0.80 times the velocity of sound. Find the frequency of sound (in Hz) received by the listener at the moment when the source gets closest to him.
