1. The problem statement, all variables and given/known data An astronomical telescope is constructed using 2 convex lenses. The objective lens is of focal length 40cm and eyepiece lens is of focal length 10cm. Let d be the distance between the 2 lenses. Draw ray diagrams for the following situations. 1.When d=50cm 2.When d>50cm 3.When 40cm<d<50cm The telescope is used to observe objects at infinity. 2. Relevant equations 3. The attempt at a solution In each situation I drew the objective lens's incident ray and the refracted ray up to its focal plane. But i do not understand how to complete them.
