They are a way of showing what happens when light is relected or refracted.
Normal - line drawn at a right angle to the boundary
The incident ray and reflected ray are always measured from the normal.
Law of reflection
1. angle of reflection = angle of incidence
2. the incident ray, reflected ray and normal ray all lie on the same plane
Light travels at different speeds in different materials. It travels faster in air than in water…
