Refraction

Refraction: demonstrations
Refraction through a semi-circular glass block A 3D simulation of the refraction of light through a semi-circular block. The angle of incidence can be varied upto and beyond the critical angle. From freezeray.com
4 Star
An interactive teaching aid to show how light is refracted by a semi-circular block. The angle of the light source can be varied up to and beyond the critical angle.
