A camera lens usually consists of a combination of two or more lenses to produce a good-quality image. Suppose a camera lens has two lenses - a diverging lens of focal length 10.7 cm and a converging lens of focal length 5.35 cm. The two lenses are held 6.79 cm apart. A flower of length 10.7 cm, to be pictured, is held upright at a distance 54.3 cm in front of the diverging lens; the converging lens is placed behind the diverging lens. a) How far to the right of the convex lens is the final image? Submit Answer Tries 0/100 b) What is the Submit Answer magnification of the final image? Tries 0/100 c) And what is the height of the final image? Submit Answer Tries 0/100
