Three observers A, B and C measure the speed of light coming from a source to be `v_A,v_B` and `v_C`. The observer A moves towards the source and C moves away from the soure at the same speed. The observer B stays stationary. The surrounding space is vacuum everywhere .

A

`upsilon_A gt upsilon_B gt upsilon_C`

B

`upsilon_A lt upsilon_B lt upsilon_C`

C

`upsilon_A = upsilon_B = upsilon_C`

D

`upsilon_B = (1)/(2) (upsilon_A + upsilon_c).`

The apaarent frequency of a note is 200 Hz when a listener is with a velocity of 40 ms^(-1) towards a stationary source. When he moves away from the same source with the same speed, the apparent frequency of the same note is 160 Hz. The velocity of sound in air in m/s is :

At what speed should a source of sound move away from a stationary observer so that observer finds the apparent frequency equal to half of the original frequency?

A source emitting a sound of frequency v is placed at a large distance from an observer. The source starts moving towards the observer with a uniform acceleration a. Find the frequency heard by the observer corresponding to the wave emitted just after the source starts. The speed of sound in the medium is v.
