(Assume the velocity of sound is )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
A musician on a moving vehicle plays a tone at 880 Hz note. i.e.; f=880 Hz When the vehicle was approaching a listner, he receives it as 888 Hz tone, i.e.;f'=888 Hz The velocity of sound is v=333 m s-1 This is the case of observer is stationary &…
