A) 385 Hz
B) 374 Hz
C) 394 Hz
D) 333 Hz
Correct Answer: B
Solution :
Velocity of source (whistle) is given by \[{{v}_{s}}=r\omega \] \[=(0.5\,m)\,(20\,rad/s)\] \[=10\,m/s\] The frequency of sound observed by the observer will be minimum when he is at point A. Thus, at this point minimum frequency of source as observed by observer isYou need to login to perform this action.
