Below is a skills checklist I created based on the syllabus, if you can do everything listed below you should be in a good position for both your school’s module 7 topic test and the HSC.

  • Understand Maxwell’s contribution to physics

  • Understand historical and contemporary experiments to determine the speed of light

  • Understand the spectra produced by discharge tubes, reflected sunlight and incandescent filaments

  • Recognise that each element has its own unique spectra

  • Understand what can be determined about a star from its spectra

  • Understand double slit diffraction both qualitatively and quantitatively

  • Compare the models of light proposed by Newton and Huygens

  • Understand Polarisation and Malus’ law

  • Understand the consequences of the ultraviolet catastrophe

  • Understand the photoelectric effect and how it advanced the model of light

  • Know the two postulates of relativity

  • Understand the effects relativity has on time, length and momentum

  • Know experiments which proved the existence of time dilation

  • Calculate the energy released by processes when mass is turned into energy
