Practise Edexcel IGCSE Physics angular measures by measuring or selecting the angle of incidence from ray diagrams in optics questions.
A student investigates the reflection of light by a plane mirror.
The student uses a ray box, a ruler, a pencil and a mirror.
The diagram shows a ray of light directed to a point on the mirror.
Measure the angle of incidence.
angle of incidence = ............ degrees
79 degrees
Accept:
- 78-80 degrees
- ECF from indicated angle of incidence in 4(b)(i), e.g. 10-12 degrees if the angle was marked between the ray and boundary
