Angle of incidence
When a ray or beam is reflected from a surface, the angle of incidence is the angle between the incident, or approaching, ray and a line perpendicular to the surface at this point. A Twig Science Glossary Film. Key scientific terms...

Manipulating Light
When light hits something, a number of things can happen: it can be reflected, refracted, diffracted or absorbed. But what does this mean? Physics - Waves - Learning Points. Manipulation of light is vital to our survival. Light waves...
