Discuss all the rules along with diagrams for image formation. Answer in 2-3 lines . Don't copy from Google. ​

Answer 1

Answer:

General rules for image formation using ray diagrams:

Any ray of light that passes through the mirror, is always parallel to the principal axis. Any ray of light that passes through the mirror always passes through the principal focus (f) of the mirror after reflection.

Answer 2

Explanation:

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.
