A train is approaching towards a platform with a speed of 10 m `s^(-1)` while blowing a whistle of frequency 340 Hz. What is the frequency of whistle heard by a stationary observer on the platform ? Given speed of sound `= 340 ms^(-1)`.

330 Hz

350 Hz

340 Hz

360 Hz

Text Solution

Verified by Experts

The correct Answer is:

`F^(1) = ((V)/(V-V_(s)))`
`= 340((340)/(340-10)) = 350.3 Hz`
