A stationary source is emitting sound at a fixed frequency f0

Sahay Sir > Question Answers > A stationary source is emitting sound at a fixed frequency f0
A stationary source is emitting sound at a fixed frequency f0 , which is reflected by two cars approaching the source. The difference between the frequencies of sound reflected from the cars is 1.2% of f0 . What is the difference in the speeds of the cars (in km per hour) to the nearest integer ? The cars are moving at constant speeds much smaller than the speed of sound which is 330ms−1 .
