Tag: reflection of light and shadow

When a light ray is reflected in many directions from a surface like a rock, it is called as diffused (or Irregular) reflection.

The reflection taking place from the walls of a building is called diffused reflection.
In diffused reflection, the reflected rays are not parallel to each other. This kind of reflection occurs from a coarse surface. Walls of a building being coarse surfaces, give rise to diffused reflections.

Reflection is defined as the optical phenomenon where light rays come back after hitting a smooth surface.

Reflection occurs when a light ray bounces back from a barrier.

A ray of light which bounces off the surface of mirror is called reflected ray.

Newton used corpuscular theory to explain reflection and refraction of light. According to Sir Isaac Newton's Corpuscular Theory a luminous body continuously emits tiny, light and elastic particles called corpuscles in all directions. When these particles fall on the retina of the eye, they produce the sensation of vision.

Normal is perpendicular drawn to the surface at the point of incidence so that angle between incident ray and normal is angle of incidence.

Normal is the line drawn perpendicular to the surface of the mirror at the point of incidence. 

Light moving in one medium when falls at the surface of another medium, part of light returns to the same medium. Some part is transmitted and the rest is absorbed.  No material is a perfect reflector. Almost all surfaces absorb some part of light.
