Physics 165/164 Homework Assignment #1 Due, Friday 1 February 2008 at the beginning of class. (Deposit in Homework Box at door to classroom.) Read pages 1 through 9 of Handout #1 (optional, read through the rest of Handout #1). Read sections 1, 2, and 3 of Handout #2. Solve Problems: 1. Two plane mirrors, one horizontal and one vertical, meet at a right angle. A laser beam is incident on the vertical mirror with an angle of incidence θ 1 =60 o as shown. Make a large sketch showing the path of the laser beam as it reFects o± these mirrors. Calculate all the angles of incidence and reFection. As the beam leaves the mirror system, how does its direction compare to that of the incident beam? 2. A diamond is submerged in one of the liquids listed in table 30.1 of Handout #2. A ray of light strikes the surface of the diamond with an angle of incidence of 31.0

Unformatted text preview: o , the angle of refraction inside the diamond is 16.4 o . What is the liquid? What would the angle of refraction be if the diamond was in air? 3. The term “dispersion” describes the fact that the index of refraction of a particular material depends very slightly on the color of the light. Quartz, for example, has an index of refraction n RED = 1 . 685 for red light and n BLUE = 1 . 615 for blue light. Two rays of light, one red and one blue, are traveling in the same direction and hit a quartz block with an angle of incidence θ 1 = 40 o . What is the angle between the red and the blue beams inside the block of quartz? Dates to remember: Exam #1, 8:30 am, Wednesday, 13 February 2008. “Imagination is more important than knowledge.” Albert Einstein....
