CAIE IGCSE Physics 3.2.1.1 Terms normal, angle of incidence and
Practise recognising the normal and measuring incidence and reflection angles correctly on plane-mirror ray diagrams.
How this is tested
- distinguish angles measured from the mirror surface from angles measured from the normal
- choose the labelled rays or angles that represent incidence and reflection in a diagram
