#Angle of reflection on a mirror how to

Mathematics - Show students how to use protractors to measure angles. Pairs of students will continue doing this until they have found and marked the places where they must stand to see both reflections in the mirror.Īngles of Reflection Explore how light reflects off of a mirror at different angles. Once students have determined where they will stand, they remove the paper from the mirror and test their predictions. They will draw diagrams in their science notebooks to show the places they have selected. Each pair will discuss and agree on the places where they think they must stand. They will be challenged to predict where two people must stand so each can see the other's reflection in the mirror. Students will then work in pairs using the student page as a guide. Making sure to use the mirror as a centerline, have students lay a 2 to 3 meters length of masking tape on the floor, extending out from, and perpendicular to, the wall. Students will mount the mirror, which should be covered with a piece of paper, flat on a wall at eye level. In other words, when light comes into contact with a mirror, the angle of reflection equals the angle of incidence. According to the law of reflection, light is always reflected at the same angle that it arrives at a surface. The angle between the reflected ray and the perpendicular is called the angle of reflection. 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
