Explanation:

REGULAR AND DIFFUSED REFLECTION - DEFINITION

concept

Regular reflection occurs at the surface of a plane surface like a plane mirror. Reflected rays after regular reflection are parallel.

Diffused reflection occurs at the surface of a rough surface like cardboard. Reflected rays after regular reflection are not parallel.

Note: Laws of reflection are valid in both the cases.

REGULAR AND IRREGULAR REFLECTION - DEFINITION

concept

Regular Reflection:

1. Reflection from a polished surface is called regular reflection.

2. parallel rays remain parallel after reflection.

Irregular Reflection:

1. Reflection from a rough surface is called diffuse reflection.

2. Parallel rays do not remain parallel after reflection.

Question

1) Explain the reflection from regular and irregular surfaces drawing ray diagrams.

Answer

Regular reflection: It is the reflection from a smooth surface such that the light rays are evenly parallel to each other and an image is formed. ... Irregular reflection: It is the diffused reflection from uneven surface such that the light rays are not parallel to each other and do not form an image.

Question

2) With a ray diagram explain the formation of image by a plane mirror.

Answer

Uses of Ray Diagrams. Ray diagrams can be particularly useful for determining and explaining why only a portion of the image of an object can be seen from a given location. The ray diagram at the right shows the lines of sight used by the eye in order to see a portion of the image in the mirror.
