Rules of obtaining image by convex lens:-

RULE 1.) If incident ray is parallel to principle axis, then the reflected ray will pass through Focus.

RULE 2) just reverse of rule 1 .

I.e if the incident ray passes through Focus, reflected ray becomes parallel to principle axis.

RULE 3) If ray of light passes through optical center of lens, reflected ray is undeviated.

happy to help!
