Caption: Optical prisms bending laser light demonstrating refraction. When light is incident from a more optically dense medium onto a less optically dense medium (for example, from glass onto air) it refracts (bends) away from the normal to the surface between the media. The angles of incidence and refraction are related through Snell's law.
