State the laws of reflection. Do these laws hold true for irregular reflection
Answers
Answer:
Laws of reflection are: (i) The incident ray, the reflected ray and the normal ray at the point of incidence, lie in the same plane. (ii) The angle of incidence is equal to the angle of reflection.
Explanation:
The law of reflection also holds for non-plane mirrors, provided that the normal at any point on the mirror is understood to be the outward pointing normal to the local tangent plane of the mirror at that point. For rough surfaces, the law of reflection remains valid. It predicts that rays incident at slightly different points on the surface are reflected in completely different directions, because the normal to a rough surface varies in direction very strongly from point to point on the surface. This type of reflection is called diffuse reflection, and is what enables us to see non-shiny objects.
Answer:
The law of reflection :-
(1.) the incident ray, reflected ray and normal meets each other at a point on same medium.
(2). Angle of incidence = angle of reflection
Explanation:
Yes this law is applicable every where in case of mirror.
