▪️What is reflection of light ? Write its laws along with the diagram.​

Answer 1

Explanation:

Whenever we look into a mirror, or squint at sunlight glinting from a lake, we are seeing a reflection. ... The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.

Answer 2

Explanation:

The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.
