Question

state and explain laws of reflection with the help of suitable diagram

Answer 1

In the diagram, the ray of light approaching the mirror is known as the incident ray (labeled I in the diagram). ... The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Answer 2

Answer:

The laws of reflection are:

(i) The incident ray, reflected ray, and the normal ray lies in the same plane at the point of coincident.

(ii) The angle of reflection is equal to the angle of reflection.

Explanation:

There are two fundamental laws for light reflection:

1. At the point of incidence, the incident ray, the reflected ray, and the normal to the reflecting surface all reside in the same plane.
2. The angle of incidence and reflection are always equal. i.e ∠ i = ∠r.

From the figure,

$I$ is the Incident ray.

$R$ is the Reflected ray.

$N$ is the normal ray.

∠ i  represents is the angle of incidence and ∠ r represents the angle of reflection.

Reflection is the sudden change in direction of propagation of wavefront that hit the boundary between different mediums.
