You are marooned on a tropical island. Design a telescope from a cardboard map tube and the lenses of your eyeglasses. One lens has a +1.0-m focal length and the other has a +0.30-m  focal length. The telescope should allow you to view an animal 100 m from the objective with the final image being formed 1.0 m from the eyepiece.

1)

Determine the required distance between lenses.

Express your answer with the appropriate units.

Build a microscope that can double the size of an object. We need to choose two converging lenses from these available lenses with focal lengths 2,4,8, and 12 meters. First choose an objective lens focal length, and a distance to place the object from the lens. Then choose an eyepiece lens focal length and a distance to place the lens from the objective lens. Draw your microscope design including a ray diagram. Your diagram should include: 1. Location and properties...
