This video explains a easy way to construct a ray diagram for reflection in a plane mirror.
The eyes alone cannot see any object. It is only when light from an object enters our eyes that we see the object. The light may have been emitted by the object, or may have been reflected by it.
This video explains about the ray tracing basics of why a flat mirror creates a virtual image behind the mirror, independent of observer location.
.This video explains the verification of the law of reflection which states "angle of incidence equals angle of reflection", sometimes called the law of reflection.The incident , the reflected and the 'normal' wave all lie in the same plane.
