A sound wave of frequency f propagating through air with a velocity C, is reflected from a surface which is moving away from the source with a constant speed V. Find the frequency of the reflected wave, measured by the observer at the position of the source.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
f' = f = 
Doppler effect between S and W
f'' = f' 
Doppler effect between W and O
= f
