MHT CET 2025 Physics question
If a source emitting waves of frequency 'F' moves towards an observer with a velocity and the observer moves away from the source with a velocity , the apparent frequency as heard by the observer will be (V = velocity of sound)
Answer: (A)
Solution
Doppler formula: (observer receding reduces the numerator, source approaching reduces the denominator). With and : $F' =
