The two laws of reflection are: (i) the incident ray, the reflected ray and the normal (at the point of incidence), all lie in the same plane. (iii) of same size as the object, (iv) as far behind the mirror as the object is in front of the mirror.

Answer 2

Reflection and refraction. Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. ... The reflected ray is always in the plane defined by the incident ray and the normal to the surface.
