![]() The angle between the incident ray and an imaginary perpendicular line drawn to the surface of the mirror is called the angle of incidence. Reflection involves two types of light rays: the incoming, or incident, ray and the outgoing, or reflected, ray. ![]() When you look at an object in a mirror, what you see is the reflection of light from that object. Mirror, Mirror on the Wall: Angles of Reflection Test your understanding of the concepts covered with the reflection and refraction problem set.Molecular Expressions: Science, Optics and You - Activities in Optics - Angles of Reflection Below is a video overview of the concepts covered. The interactive illustration at the top of this page explores patterns of reflection and refraction of light rays that hit a variety of interfaces at different angles of incidence. A light ray with an angle of incidence equal to or greater than the critical angle will reflect, following the law of reflection.
