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

  1. To improve:

    For the semicircular glass block it would be good if your diagram showed what happened when:
    i (angle of incidence)greater than c (critical angle)= TIR
    i (angle of incidence)less than c (critical angle)= refraction

    For the equilateral triangular prism (dispersion) you need to show the ray spliting into the 7 colours of the spectrum - red on the top and violet on the bottom.
