Question

4 rules for tracing the image formed by concave mirror

Answer 1

Explanation:

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.

Answer 2

Answer:

one more is that

when Ray is incident at the pole or centre of the mirror, the mirror acts like a plane mirror and the Ray reflects with the same angle with which it was incident
