A) 270 Hz
B) 273 Hz
C) 383 Hz
D) 300 Hz
Correct Answer: B
Solution :
Apparent frequency, when source is moving and observer is stationary \[n=n\left( \frac{V}{V+{{V}_{s}}} \right)\] \[n=300\,\left( \frac{330}{330+30} \right)\] \[=300\left( \frac{330}{360} \right)=300\times 0.91\] \[=273\,Hz.\]You need to login to perform this action.
