Question

proof for law of reflection

Answer 1

Explanation:

The incident and reflecting rays has been shown with direction. According to fermat's principle the time taken by a ray will be maximum or minimum. Using this principle the laws of reflection i.e. angle of incidence is equal to angle of reflection has been derived.

Answer 2

Answer࿐

Laws of reflection:-

1st law:-The incident ray, the reflected ray,and the normal at the point of incidence lie on the same plane.

2nd law:- The angle of incidence is equal to the angle of reflection.
