1. As an object is moved from a distant location toward the center of curvature of a concave mirror its image: A) remains virtual and becomes smaller D) remains real and becomes larger B) remains virtual and becomes larger E) changes from real to virtual C) remains real and becomes smaller Ans: D 2. An object is 30 cm in front of a converging lens of focal length 10 cm. The image is: A) real and larger than the object B) real and the same size than the object C) real and smaller than the object D) virtual and the same size than the object E) virtual and smaller than the object Ans: C 3. The light waves represented by the three rays shown in the diagram all have the same frequency. 4.7 wavelengths fit into layer 1, 3.2 wavelengths fit into layer 2, and 5.3 wavelengths fit into layer 3. Rank the layers according to their indices of refraction, least to greatest. A) 1, 2, 3 B) 2, 1, 3 C) 3, 1, 2 D) 3, 2, 1 E) 1, 3, 2 Ans: B 4. Waves from two slits are in phase at the slits and travel to a distant screen to produce the second minimum of the interference pattern. The difference in the distance traveled by the wave is: A) half a wavelength D) two wavelengths B) a wavelength
