Question

rules for drawing ray diagrams in spherical mirror

Answer 1

Hi friend ,
The revised rules can be stated as follows:

1. Any incident ray traveling parallel to the principal axis on the way to a convex mirror will reflect in such a manner that its extension will pass through the focal point.
2. Any incident ray traveling towards a convex mirror such that its extension passes through the focal point will reflect and travel parallel to the principal axis.

Answer 2

Answer:

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.
