You want to make a telescope and have two lenses: Lens L1 with f1 = -20 mm and lens L2 with f2 = 60 mm. What is the separation between the two lenses to look at objects near infinity? (b) What is the magnification of the telescope, the type of telescope and is the image erect or inverted? (c) Draw a diagram showing where parallel light rays entering lens 1 are focused, and where those parallel rays appeared coming out of lens L2.
