Question

A light ray paraller to the principal axis reflected from the mirror. Drow the reflected ray and show the directions

Answer 1

Answer:

All the rays parallel to the principal axis of a concave mirror always pass through the focal point of the mirror after reflection

Explanation:

In the case of convex mirror: A ray parallel to principal axis appears to diverge from the principal focus after reflecting from the surface of a convex mirror. Similarly, all rays parallel to the principal axis of a convex mirror appear to diverge or coming from principal focus after reflection from a convex mirror.

Answer 2

$\boxed{\huge{\mathfrak\red{ ANSWER :-}}}$

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.
