H2 Physics: Superposition structured questions

Written practice in interference, diffraction gratings, standing waves, intensity and polarisation. Five questions are selected for each attempt.

  • GCE A-Level H2 Physics 2027

Learning objectives

  • Apply the principle of superposition to resultant displacement.
  • Explain standing-wave formation, nodes, antinodes and energy transfer.
  • Apply boundary conditions to standing waves on stretched strings.
  • Analyse displacement and pressure patterns in resonant air columns and determine sound wavelength.
  • Explain single-aperture diffraction and apply first-minimum and Rayleigh criteria.
  • Relate phase difference to separations in time and position.
  • Explain coherent two-source interference using phase and path difference.
  • Analyse Young double-slit interference and its small-angle assumptions.
  • Use diffraction gratings to analyse principal maxima and determine wavelength.

Practise

Questions are picked at random each time you start. You'll see the answer after each question. It's for practice only and doesn't count towards course progress.
