Rules of Image formation by Spherical Lenses

Definition

1. If incident ray is parallel to the principal axis, then the reflected ray passes through focus.
2. If the incident ray passes through focus, then the reflected ray will be parallel to the principal axis.
3. If the incident ray is passed through the optical centre, it will pass without refraction
