A) 500 Hz
B) 550 Hz
C) 355 Hz
D) 55.5 Hz
Correct Answer: B
Solution :
\[\begin{align} & \text{}\xrightarrow{{{\text{v}}_{\text{s}}}\text{=30}\,\,\text{m/s}}\,\,\,\,\,\,\,\underset{{{v}_{o}}=0}{\mathop{\text{Observer}}}\, \\ & \text{Source} \\ \end{align}\] Here,\[n=500\,\,Hz,\,\,{{v}_{o}}=0\] \[{{v}_{s}}=30\,\,m/s,\,\,v=330\,\,m/s\] \[\therefore \]From, \[n=n\left( \frac{v-{{v}_{o}}}{v-{{v}_{s}}} \right)\] \[=500\left( \frac{330}{330-30} \right)\] \[=550\,\,Hz\]
