Question

Differentiate between regular and diffused reflection. Does diffused reflection mean the failure of the laws of reflection?

Answer 1

Light reflects from a smooth surface at an equivalent angle because it hits the surface. The angle of incidence and angle of reflection make the same angle as the normal which is perpendicular to the surface of reflection. When the light throws perpendicular to any surface, it is reflected straight back in the direction of the source, thus forming zero angles.

Complete step-by-step solution:
Regular reflection - The regular reflection is the reflection of rays once they meet (fall on) a smooth (uniform) and glistening surface, where the incident light rays are reflected in a single direction, when a beam of parallel light rays is incident on a smooth & plane surface, the reflected rays also will be parallel, and it's called the regular reflection.
1. In regular reflection, the reflected rays are parallel to every other.
2. Regular reflection occurs from a nicely polished regular reflective surface.

Diffused reflection- Diffuse reflection is that the reflection of sunshine or other waves or particles from a surface such as a ray incident on the surface is scattered at many angles instead of at only one angle as within the case of specular reflection.
1. In diffused reflection, the reflected rays aren't parallel to every other.
2. This reflection occurs from a diffused or irregular surface.

In diffused reflection, the surface is rough. Laws of reflection hold. The reflected rays scatter in several directions, due to irregularities on the surface.
The laws of reflection require the angle of incidence and therefore the angle of reflection to be an equivalent and for the incident ray, the traditional at the purpose of incidence and therefore the reflected ray to all or any dwell an equivalent plane. So to conclude, diffused reflection doesn't mean the failure of the laws of reflection.

Note: Specular reflection is where light is reflected off a smooth surface. The Laws of Reflection still apply but because the tradition of the surface is all on different angles, light is scattered or diffused. Specular reflection can be contrasted with diffuse reflection, in which light is scattered away from the surface in a range of different directions.
