Question

A sound wave strikes a mirror at an angle of 30 degree calculate the angle between the incident ray and the reflected ray

Answer 1

angle of incidence = angle of reflection

here angle of incidence = angle of reflection= 30°

so the angle between the incident ray and the reflected ray = 30° + 30°

                                                                                                   = 60°

Answer 2

Hello Everyone

Here it said that the incidence rays stike the surface at 30°
