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.

1. A ray of sunlight is passing from diamond into crown glass; the angle of incidence is 35.00°. The indices of refraction for the blue and red components of the ray are: blue (ndiamond = 2.444, ncrown glass = 1.531), and red (ndiamond = 2.410, ncrown glass = 1.520). Determine the angle between the refracted blue and red rays in the crown glass. 2. An object is 25 cm in front of a diverging lens that has a focal length...

A. The human eye 1. Whenever a normal eye forms an image, the image distance will always equal the distance from the cornea and eye lens to the retina (~25 mm), regardless of how far away the object is located. Explain why the image distance cannot change. 2. If the image distance must change, then what intrinsic property of the eye lens must change in order for the eye to focus on objects at different distances? Hint: read the Introduction....
