A speaker emits a sound wave of frequency `f_(0)`. When it moves towards a stationary observer with speed u, the observer measures a frequency `f_(1)`. If the speaker is stationary, and the observer moves towards it with speed u, the measured frequency is `f_(2)`. Then -

A

`f_(1)=f_(2)=f_(0)`

B

`f_(1)gtf_(2)`

C

`f_(1)ltf_(2)`

D

`f_(1)=f_(2)gtf_(0)`
