Question

angle of incidence=angle of reflection.this rule is given expained by

Answer 1

it only happens when the mirror is smooth and polished and this phenomenon of light is called regular reflection.explanation - when a Ray of light strikes a smooth and polished surface example mirror it reflects back ,this process is called reflection of light and Ray of light which strikes the smooth surface is called the incident ray and the Ray of light which reflects back is called the reflected ray and when the surface is smooth and polished the angle of reflection is equals to the angle of incidence.
