3.17 Refraction of light, Experiments

Describe experiments to investigate the refraction of light, using rectangular blocks, semicircular blocks and triangular prisms.

This worksheet show's how light is refracted through different perspex/glass blocks

Notice that in the prism diagram Red is refracted the least and Violet the most

EXTRA: Here is an interesting video showing some cool stuff you can do with refraction.


  1. The anticipation is killing me!

  2. Brilliant!
    As 42 deg is the critical angle for glass I think it should be refracted through 90 degs.
    The situation you've drawn is for angles larger than 42 deg.
