Question Description
A stationary source is emitting sound at a fixed frequency f0, which is reflected by two cars approaching thesource. The difference between the frequencies of sound reflected from the cars is 1.2% of f0. What is thedifference in the speeds of the cars (in km per hour) to the nearest integer ? The cars are moving at constantspeeds much smaller than the speed of sound which is 330 ms-1.Correct answer is '7'. Can you explain this answer? for JEE 2024 is part of JEE preparation.
