Question
An observer starts moving with uniform acceleration 'a' towards a stationary sound source of frequency f. As the observer approaches the source, the apparent frequency f' heard by the observer varies with time t as:
Options
A.
B.
C.
D.
Solution
Sol. v0 = at
f =$\left( \frac{v + v_{0}}{v} \right)f_{0} = \left( \frac{v + at}{v} \right)f_{0}$
