An observer is moving with half the speed of light towards a stationary microwave source emitting waves at frequency 10 GHz. What is the frequency in GHz of the microwave measured by the observer?
(speed of light =3×108 ms−1). Answer the nearest integer.
Speed of observer V=C2
where speed of Microwave is C
Original frequency of source is given as f0=10 GHz
Using relativistic Doppler effect in case observer moves towards the stationary source.
Apparent frequency measured by observer f′=f0√C+vC−v
