Year 12
Side B2b: Superposition
Continue Side B waves with phase difference, interference, Young's double slit, diffraction, and stationary waves.
Part of Year 12 CIE Physics 9702.
Topic Overview
What students will cover
This topic should develop the full superposition model with clear diagrams and standard examples. Students need to compare wave overlap, interference, diffraction, and stationary patterns without losing the shared logic behind them.
