- 2.0 marks for incorrect answer
Hint
The ray diagram shows the path of light as it passes through a prism. The angles marked in the diagram are , , , , and . The angle of incidence () is the angle between the incident ray and the normal to the surface of the prism. The angle of emergence () is the angle between the emergent ray and the normal to the surface of the prism. The angle of deviation () is the angle between the incident ray and the emergent ray. The angle of refraction () is the angle between the refracted ray and the normal to the surface of the prism. The angle of reflection () is the angle between the reflected ray and the normal to the surface of the prism. The correct answer is (c) , and .
Quick oral answer
The correct answer is (c) , and .
Common mistakes
- 1.confusing angle of incidence with angle of emergence
- 2.confusing angle of deviation with angle of refraction
- 3.confusing angle of reflection with angle of incidence
