Learning objects Optics and prisms: materials

TLF ID L1481

Position a prism to split white light into its component colours. Test whether the colours seen are affected by the prism material: glass, flint glass or diamond. Explain why dispersion occurs in all of the prism materials. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.



Educational details

Key learning objectives
  • Students use a triangular prism to split white light into the visible spectrum.
  • Students explain the dispersion of white light by referring to its composition and differential refraction of colours.
  • Students compare the dispersion produced by prisms of different materials.
Educational value
  • Introduces the principles of refraction, dispersion and total internal refraction of light.
  • Students engage with a simulation of white light dispersing as it passes through a triangular prism.
  • Students manipulate the position, orientation, composition, size and shape of prisms to observe how these affect light rays.
  • Students choose between two hypotheses.
  • The simulation is accessible for further investigation after feedback has been given.
