A driver is riding a car with velocity `v_c` between two vertical walls on a horizontal surface as shown in figure.A source of sound of frequency 'f' is situated on the car. (`v_c lt lt v`, where v is the speed of sound in air )

Beat frequency observed by the driver corresponding to sound waves reflected from wall-1 amd wall-2 (reflected waves corresponding to waves directly coming from source ):

A driver is riding a car with velocity v_c between two vertical walls on a horizontal surface as shown in figure.A source of sound of frequency 'f' is situated on the car. ( v_c lt lt v , where v is the speed of sound in air ) Consider the sound wave observed by the driver directly from car has a wavelength lambda_1 and the sound wave after reflection from wall-1 observed by the driver has wavelength lambda_2 then (lambda_1-lambda_2)/(lambda_1+lambda_2) is :
