Unformatted text preview: Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 10A 1. The lens inside a projector forms an image on a screen. Is the image created a real or virtual image? Solution : The image is formed at the location of the screen and the light of the image actually strikes the screen, so by definition the image is real. Also, image formed on the other side of the lens is real. 2. A light beam travels from water (n = 1.33) into a quartz (n = 1.54) triangle shaped prism and then strikes the interface between the two media at the bottom surface at the critical angle θ C of total internal reflection. What is the original angle θ ? (The two normal lines to the surface have been drawn for completeness and the lines extended for your convenience) Solution : Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 10B 1. A light wave is traveling in diamond (n= 2.42) and approaches the boundary of a surrounding body of water (n=1.33). Is the phenomenon of total internal reflection...
