The angle of the light ray is measured from the normal, as was the case with reflection. If the speed slows across the boundary, the refracted angle will be smaller – the light ray will bend toward the normal.. Define refractive index.. Demonstrate refraction..

When a wave reaches a boundary between two media, usually some or all of the wave bounces back into the first medium.. A metal surface is rigid to light waves that shine upon it. . Light . LIGHT.

Refraction of Light - Defined. Refraction of light occurs when a light wave moves from a vacuum (or a medium) into another medium (or a vacuum). When a wave changes media, its ____________ changes..
