Converging
First, draw an incident ray parallel to the main axis, then extend the reflected ray. [Make sure that it will pass through the focal point behnd the lens] Next, draw a ray that will pass through the focal point, when it reaches the lens, extend it parallel to the main axis. Do the same thing on the tail of the object. Connect the intersection and that will be your image.
Diverging
Draw three incident rays travelling towards the lens. Then, refract them according to the three rules of refraction. Extend their reflections to get the intersection. Do tha same thing for the other side. Connect the intersections.
**RULES of REFRACTION**
-Any incident ray travelling parallel to the principal axis of a diverging lens will refract through the lens and travel in line with the focal point (in a dirction such that its extension will pass through the focal point0.
-Any incident ray travelling towards the foacal point on the way to the lens will refract through the lens and travel parallel through the main axis.
-Any incident ray passing through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
