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.

    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.
