A sound source producing waves of frequency 300 Hz and wavelength 1 m observer is stationary, while source is going away with the velocity $30 m / s$ , then apparent frequency heared by the observer is

Options:

Answer:

Solution:

Apparent frequency $n^{'} = n (\frac{v}{v + v _{s}})$ $v v_{s} = velocity of sound, = velocity of source$ $∴ n^{'} = 300 (\frac{332}{332 + 30}) = 273 Hz$
