Topic 1
Wave answers are best when source, field orientation, propagation, and application are linked together.
Topic 2
Ray-optics answers should connect ray path, formula, sign convention, and image interpretation.
Topic 3
Wave-optics answers improve when superposition and path-difference ideas are stated explicitly.
Topic 4
Modern-physics answers are strongest when experiment, model, and conclusion are linked directly.
Topic 5
Semiconductor answers become clear when charge carriers, junction behaviour, and device function are linked in one...
