A plane sound wave is generated in a medium along the x axis whose equation is given by y A cos ot kx If c is speed of wave in the medium there is a reference frame S which is moving with uniform acceleration a in ve direction of x axis at t 0 both wave and reference frame S coincide with each other at origin The equation of wave in reference wave S is A y Acos at 1 B y Asin ot 1 at 2c at 2c y Asin oot kx kx at C y Acos eot 1 21 kx 2c not 1 at kx
