The frequency changes by `10%` as the source approaches a stationary observer with constant speed `v_S`, What sould be the percentage change in ferquency as the source recedes from the observer with the same speed? Given that `v_Sltltv` (v speed of sound in air).

the frequency changes by 10 % as the source approaches a stationary observer with constant speed v_(s) . What would be the percentage change in frequency as the sources reaccedes the observer with the same speed ? Given , that v_(s)lt lt v (v= speed pf sound in air )

A source is approaching towards an observer with constant speed along the line joining them. After crossing the observer, source recedes from observer with same speed. Let f is apparent frequency heard by observer. Then,

when a source of sound of frequency f crosses stationary observer with a speed v_(s) (lt lt speed of sound v) , the apparent change in frequency Dealtaf is given by

when a source of sound of frequency f crosses stationary observer with a speed v_(s) (lt lt speed of sound v) , the apparent change in frequency Δf is given by

A source of sound of frequency 90 vibrations/ sec is approaching a stationary observer with a speed equal to 1/10 the speed of sound. What will be the frequency heard by the observer
