REFLECTION OF LIGHT

when a light hits the smooth surface it will be reflected in this way, the angle of incidence must be equal to the angle of reflection according to the law of reflection.however when it hits the curved surface it will bounce back to different direction.law of reflection also states that the incident,normal and reflected rays all lie on the same plane.incident rays are those which hits the smooth surface such as mirror and reflected rays are those which make the angle equal to the incident rays.there are two kinds of reflection of light i.e regular reflection and diffused reflection.regular reflection is the reflection of light from the smooth surface while irregular reflection is the reflection of light from the uneven surface.
