929 Chapter 32 Optical Images Conceptual Problems 1 Determine the Concept Yes. 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 Concept Yes; 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 Concept Let 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 > 2 f , the image is real, inverted, and smaller than the object. ( d ) If f < s < 2 f , the image is real, inverted, and larger than the object. 5 •• Determine the Concept A convex mirror always produces a virtual, upright image that is s than the object. It never produces an enlarged image.
