Reflection of Light
Reflection is the turning back of the light from the surface it hits. Incoming and reflected lights have same angle with the surface. If the surface reflects most of the light then we call such surfaces as mirrors. Examine the given pictures below. They show regular and diffuse reflection of light from given surfaces.
Laws of Reflection
1. First law of reflection states that; Incident ray, reflected ray and Normal to the surface lie in the same plane.
2. Angle of incident ray is equal to the angle of reflection ray.
Example: Find the angle of incident ray from the given information in picture?
