A) Apparent frequency will be less than the real frequency
B) Apparent frequency will be greater than the real frequency
C) Apparent frequency will be equal to real frequency
D) Only the quality of sound will change
Correct Answer: B
Solution :
Apparent frequency in this case\[n'=\frac{n(v+{{v}_{O}})}{v}\] \[\because \] \[\frac{v+{{v}_{0}}}{v}>1\] Þ \[\frac{n'}{n}>1\] i.e. \[n'>n\].You need to login to perform this action.
