Because the light ray chooses the shortest path to its destination, the angle of incidence equals the angle of reflection. Fermat's principle describes how light behaves. When a light ray is reflected from a plane surface, it exhibits the same behaviour. As a result, the incidence and reflection angles are the same.
Question : The _______ of a ray is the angle measured from the reflected ray to the normal surface.
Option 1: Angle of Diffusion
Option 2: Angle of Reflection
Option 3: Angle of Incidence
Option 4: Angle of Refraction
