Mastery checklist
Know what success looks like.
- 01
Label the wave or ray diagram with the quantities and boundary conditions that matter.
- 02
Relate frequency, period, wavelength, speed, phase, or angle using the correct model.
- 03
Predict how the observable pattern changes when one controlled variable changes.
Exam lens
Build, apply, check.
22 Quantum physics sits inside A Level extension. Build the concept first, then practise selecting a model, showing working, and checking the final result.
