Laws of Reflection

Let us now quickly revise this chapter.

Laws of Reflection: Let us recall the laws of reflection which state –

The angle of incidence is equal to the angle of reflection, and

The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane.

Note that these laws of reflection are obeyed by all types of reflecting surfaces
