Answer:
Explanation:
The source is approaching the observer which is moving away from the source , so applying Doppler's effect
[tex]n = n_o\frac{V-V_O}{V-V_S}[/tex]
where n is apparent frequency , n₀ is original frequency , V₀ is velocity of observer , V_S is velocity of source , V is velocity of sound
Putting the given values
= [tex]n = 536\frac{340-53.7}{340-53.7 }[/tex]
= 536
So apparent frequency will be same as original frequency .
ie 536 .
