Question
Explain the differences between regular and irregular reflection light.
Solution
Regular reflection of light | Irregular reflection of light |
This type of reflection occurs on smooth surfaces such as a plane mirror. | This type of reflection occurs on rough surfaces such as a blackboard. |
In this type of reflection, the reflected rays are parallel to each other. | In this type of reflection, the reflected rays are non-parallel to each other. |
In this type of reflection, the reflected rays are in one direction. | In this type of reflection, the reflected rays are in a different direction. |
