20%] A simple telescope is to be built with an objective lens and an eyepiece to view an object that is far away as shown in Figure 1. The focal length of the objective lens is, fo = 300 20 (mm), and the focal length of the eyepiece is fe = 50 3 (mm). Use ray tracing to show how the green, blue, and red lines are affected by the objective and eyepiece lenses of the telescope. Note that the rays on the right side of the eyepiece must be parallel for the telescope to work correctly
