Physics 214 Summer 1993 Next week's lab is from the Lab Manual: the first part of experiment #2, on polarization, and all of #3. There will be one setup of the birefringence part of experiment #2, for anyone who wants to play with it. Assignment #6 (due Tuesday, July 20) 1. A plane mirror, oriented vertically facing the Sun, throws a rectangular patch of sunlight on the floor in front of the mirror. The size of the mirror is 50 cm by 50 cm, and its bottom rests on the floor. If the Sun is 50° above the horizon, what is the size of the patch of sunlight on the floor? 2. 31-39. 3. Because of refraction in the plate of glass, an object viewed through an ordinary window will seem somewhat nearer than its actual distance.

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....
