929 Chapter 32 Optical Images Conceptual Problems 1 •Determine the ConceptYes. Note that a virtual image is ″seen″because the eye focuses the diverging rays to form a real image on the retina. Similarly, the camera lens can focus the diverging rays onto the film.2 • Determine the ConceptYes; the mirror image is a left-handed coordinate system.3 •• (a) False. The virtual image formed by a concave mirror when the object is between the focal point and the vertex of the mirror depends on the distance of the object from the vertex. (b) False. When the object is outside the focal point, the image is real. (c) True. (d) False. When the object is between the center of curvature and the focal point, the image is enlarged and real.*4 •• Determine the ConceptLet s be the object distance and f the focal length of the mirror. (a) If s< f, the image is virtual, upright, and larger than the object. (b) If s< f, the image is virtual, upright, and larger than the object. (c) If s> 2f, the image is real, inverted, and smaller than the object. (d) If f < s< 2f, the image is real, inverted, and larger than the object. 5 •• Determine the ConceptA convex mirror always produces a virtual, upright image that is sthan the object. It never produces an enlarged image.
