Question

Discuss the three rule with the help of ray diagram to obtain image formed by concav mirror and convex mirror

Answer 1

Answer:

Explanation:

To draw these diagrams, we will have to recall the two rules of reflection for concave mirrors:

Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.

Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.

Earlier in this lesson, the following diagram was shown to illustrate the path of light from an object to mirror to an eye.

Answer 2

Explanation:

PHYSICS

Write the rules used for drawing ray diagrams for the formation of an image by a concave mirror.

ANSWER

The rules used for drawing ray diagrams for the formation of an image by a concave mirror are:

Rule 1: If the incident ray is parallel to the principal axis then the reflected ray passes through the focus of the concave mirror.

Rule 2: If the incident ray passes through the focus of the concave mirror, the reflected ray is parallel to the principle axis.

Rule 3: If the incident ray passes through the centre of curvature of the concave mirror, the reflected ray traces the same path.
