Superposition written questions
Work through H2 Physics interference, diffraction and stationary-wave questions, then assess written answers with marking guidance.
Learning goals
- 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.
