Question

Answer the following:

What are the rules used for drawing ray diagrams for the formation of image by spherical mirror?

Answer 1

The rules used for drawing ray diagrams are as follows.
i.If the incident ray is parallel to the principal axis, then reflected ray passes through the focus.
ii.If the incident ray passes through the focus then the reflected ray becomes parallel to the principal axis.
iii.If the incident ray passes through the centre of the curvature, the reflected ray traces the same path.
