Question

Explain the following terms a Plane mirror b Incident ray c Reflected ray d Angle of incidence and e Angle of reflection

Accepted Answer

a Plane mirror It is highly polished and a smooth reflecting surface that is prepared from a clear plane glass sheet which is usually thin and silvered with appropriate reflecting abrasive on one of the sides After pasting the glass turns opaque but because of the reflecting property of the abrasive the plane glass sheet turns into a plane glass mirror or plane glass reflector b Incident ray it is the light ray that strikes a reflecting surface c Reflected ray it is the light ray that is obtained after reflection from the surface in the same medium in which the incident ray is travelling d Angle of incidence it is the angle which the incident ray makes with the normal at the point of incidence It is denoted by i e The angle of reflection it is the angle made by the reflected ray with the normal at the point of incidence It is denoted by r
