1. The King David High School Science Department Reflection and Refraction By Mr Jones
2. Reflection For light reflecting off a plane mirror (flat, smooth, shiny): Normal Reflected Ray Incident Ray The normal is a line drawn at right angles (perpendicular) to the surface. i r Mirror = Angle of reflection (r) Angle of incidence (i)
3. Reflection For light reflecting off a plane mirror (flat, smooth, shiny): Mirror = Angle of reflection (r) Angle of incidence (i)
7. As light passes from a more optically dense material into a less optically dense material it moves away from the normal. Normal Incident Ray Less optically dense More optically dense More optically dense Less optically dense Emergent Ray Normal
