A) 286.5 Hz
B) 481.2 Hz
C) 489.3 Hz
D) 434.2 Hz
Correct Answer: D
Solution :
Here: Frequency of siren \[n=500\,Hz\] Speed of siren \[=50\text{ }m\text{/}s\] The frequency heard from siren when it is going away from listener \[n=\frac{v}{v+{{v}_{s}}}n=\left( \frac{330}{330+50} \right)500=434.2\,Hz\] (where \[\upsilon =\] velocity of sound = 330 m/s)You need to login to perform this action.
