Light refraction

Law of refraction

Refraction of light occurs when light passes from one medium to another, which usually involves a change of direction. The angle of incidence and the angle of refraction are related by Smell's law. Observe the result of changing the angle of incidence and the index of refraction.

Change of medium I

In this simulation you can observe the different parameters involved in the refraction of a light ray when changing medium.

Change of medium II


See what happens when you pass light through a material other than air. Try changing to different shapes and see how light behaves differently in each case. Why does white light break down into colors?

Reflection and refraction laboratory

Explore the bending of light between two media with different refractive indices. See how changing from air to water to glass changes the angle of reflection. Play with prisms of different shapes and create a rainbow.
