Multiple-choice questions may continue on the next column or page find all choices before answering. I posted the Homework a little earlier, so that you can have a look at it. The Discussion session will start on Thursday next week and the due day for the Homework is Feb 02 001 10.0 points Diamond has a high index of refraction at about 2 . 4, which helps account for its sparkle. How fast does light travel through a dia- mond? The speed of light in a vacuum is 3 10 8 m / s. Answer in units of m / s. 002 (part 1 of 2) 10.0 points Given: A ray approaching an interface. glass air What is the approximate refracted ray? 1. glass air 2. glass air 3. glass air 4. None of these 003 (part 2 of 2) 10.0 points glass air What is the approximate refracted ray? 1. glass air 2. glass air 3. glass air 4. None of these 004 (part 1 of 2) 10.0 points Consider the case in which light ray A is in- cident on mirror 1 , as shown in the figure. luu (nml299) WH01 markert (58710) 2 The reflected ray is incident on mirror 2 and subsequently reflected as ray B. Let the an- gle of incidence (with respect to the normal) on mirror 1 be A = 47 and the point of incidence be located 20 cm from the edge of contact between the two mirrors....
