Question

what is law of reflection?

Answer 1

1.The angle of incidence is equal to the angle of reflection

2.the incedance ray the reflected ray and normal all lie in same plane

Answer 2

there are three laws of reflection
1.If a incident ray is parallel to principal axis then reflected ray pass through focus
2.If incident ray is passing through focus then reflected ray is parallel to principal axis
3.If incident ray is passing through centre of curvature then reflected ray will occupy same path
