A) \[{{n}_{1}}=10\,n\]
B) \[{{n}_{1}}=0\]
C) \[{{n}_{1}}=0.1\,n\]
D) \[{{n}_{1}}=-0.1\,n\]
Correct Answer: B
Solution :
When velocity of source (vehicle) is perpendicular to the line joining the observer and source, then there is no Doppler's effect of sound or, there is no change in apparent frequency. Therefore, \[{{n}_{1}}=0\].You need to login to perform this action.
