A)
B)
C)
D)
Correct Answer: B
Solution :
\[\upsilon =\]velocity of sound. \[{{f}_{1}}'=\frac{\upsilon }{\upsilon -u}f\] When source moves towards stationary observer. \[f'=\frac{\upsilon }{\upsilon +u}f\] When source moves away from observer. \[{{f}_{1}}'>f'\] \[f\]does not depend on time elapse (t).You need to login to perform this action.
