Differentiate between regular and diffused reflection. Does diffused reflection mean the failure of the laws of reflection? Explain?
Hint:In order to answer this question, to know the difference between regular and diffused reflection, first we will explain the difference between them and then we will explain whether the diffused reflection breaks the laws of reflection or not.
Complete answer: The difference between regular reflection and the diffused reflection are as follows:
Regular reflection occurs when all of the parallel rays reflected from a plane surface are parallel.
Diffused or irregular reflection occurs when all of the parallel rays reflected from a plane surface are not parallel.
Reflection from a smooth surface like that of a mirror is an example of regular reflection.
Reflection from a rough surface, like that of cardboard, is an example of irregular reflection. It is caused by the irregularities in the reflecting surface.
Images are formed by regular reflection.
Images are not formed by irregular reflection.
The laws of reflection are not broken or violated in diffused reflection. The surface from which diffused reflection has microscopical irregularities, which means that the surfaces at the points where each ray is reflected are not parallel to one another. The laws of reflection are followed in every situation. Hence, diffused reflection does not mean the failure of the laws of reflection. It is caused by irregularities in the reflecting surface.
Note:For parallel incident rays, the reflected rays are not parallel to each other in diffused reflection. This is due to the reflecting surface's microscopic irregularities. As a result, the incident rays that are parallel reflect in various directions. However, the laws of reflection apply to each individual ray.
