Unformatted text preview: (a) Consider rays that strike the glass at a small angle of incidence (nearly normal). Show that if an object is at a distance l from a window, the image is at a distance that is shorter by an amount D l = (1 - 1/n)d, where n is the index of refraction of the glass and d is the thickness of the glass. (b) What change in distance does this formula give if the windowpane is ordinary glass (d=2.0 mm, n = 1.5)? (c) What change in distance does this formula give if the windowpane is heavy plate glass (d=8.0 mm, n = 1.5)? 4. 31-37. 5. 31-46. 6. 31-31. A precise ray diagram would entail using graph paper and a straightedge. 7. 31-32. A precise ray diagram would entail using graph paper and a straightedge....
