When light strikes a mirror it bounces off. This is called reflection of light. When you look at an object in a mirror, you are seeing the reflection of light from the object. The angle between the incident ray and an imaginary perpendicular line drawn to the surface of the mirror is called the angle of incidence. The angle between the reflected ray and the perpendicular is called the angle of reflection.
Light is reflected at the same angle that it strikes the mirror.
The angle of reflection is always exactly equal to the angle of incidence. This is called the Law of Reflection . In this activity, students will explore the law of reflection by trying to guess where two people must stand so each can see the other s reflection in a mirror. Students mount the mirror flat on a wall with masking tape. The mirror should be at eye level covered with a piece of paper.
