Question

give the angle of incidence and angle of reflection for normal incidence

Open in App

Solution

Normal is a perpendicular line drawn on a plane surface and all the angles of incident and reflected ray are calculated from the normal and angle of incidence is equal to the angle of reflection and if both fall normally on mirror no angle will be created and so the angles will be zero
