Light is visible electromagnetic radiation that is almost everywhere around us. It is sometimes taken for granted. This visible electromagnetic radiation consists of particles called photons, which are tiny groups of energy that move at the speed of light.
A plane or flat mirror is a reflective surface, usually made of glass and metal. Light that strikes a plane mirror follows the Law of Reflection. The Law of Reflection states that the angle of incidence is equal to the angle of reflection. The light strikes the plane mirror at the point of incidence. The perpendicular line from the point of incidence is called the mirror's normal. The angle from the mirror's normal and the point of incidence is called the angle of incidence. The angle between the ray of light leaving the plane mirror and the normal is the angle of reflection.
