Question
A source and an observer are approaching one another with velocity $4 m / s$. If the true frequency is $1200 Hz$ , deduce the observed frequency under the following conditions:
i. All velocity is in the source alone.
ii. All velocity is in the observer alone.
Take the velocity of sound waves in air to be $340 ms^{-1}$.
i. All velocity is in the source alone.
ii. All velocity is in the observer alone.
Take the velocity of sound waves in air to be $340 ms^{-1}$.
