Explain the differences between regular and irregular reflection light.

In regular reflection of light, reflection occurs on surfaces that are smooth like a plane mirror. In irregular reflection of light, reflection occurs on surfaces that are rough like a blackboard. Table states Differences between regular and irregular reflection light:

Regular reflection of light

Irregular reflection of light

Smooth surfaces, like a plane mirror, can reflect this kind of light.

This kind of reflection happens on abrasive surfaces like a blackboard.

The reflected rays in this kind of reflection are parallel to one another.

The reflected rays in this kind of reflection are not parallel to one another.

The reflected rays in this kind of reflection all point in the same direction.

The reflected rays in this type of reflection are pointed in a different direction.

Reflection of light

  • When a light beam strikes a polished, smooth surface and bounces back, it is known as light reflection.
  • After striking the surface, the incident light rays reflect off of it.
  • The ray that bounces back is known as the reflected ray.
  • A perpendicular would be normal on a reflecting surface.
  • A clear and sharp reflection is produced by specular or regular reflection.

Summary:

Explain the differences between regular and irregular reflection light.

Regular light reflection takes place on flat surfaces, such as a plane mirror. Reflection on uneven surfaces, like a blackboard, causes erratic light reflection.
