A) 270 Hz
B) 273 Hz
C) 383 Hz
D) 300 Hz
Correct Answer: B
Solution :
Apparent frequency\[n=n\left( \frac{\upsilon }{\upsilon +{{\upsilon }_{s}}} \right)\] \[\upsilon =\] velocity of sound, \[{{\upsilon }_{s}}=\]velocity of source \[\therefore n=300\left( \frac{332}{332+30} \right)=273Hz\]You need to login to perform this action.
