Homework 12 Problem 10:   Two lenses are mounted d = 27 cm apart on an optical bench. The focal length of the first lens is f1 = 5.1 cm and that of the second lens is f2 = 4.4 cm. An object of height ho = 3.5 cm is placed at a distance of do = 21 cm in front of the first lens. Part (a)  Ignoring the second lens for now, at what distance, in centimeters, behind the first lens is the object’s image formed by that lens? di = ______ Part (b)  Calculate the magnification of that image, including its sign. m = ______ Part (c)  Now consider the two-lens system and the final image it forms, i.e., the image created by the second lens. What is the distance, in centimeters, between the object and its final image? D = ______

The image of the coin in the figure is magnified by a factor of M = 4.7 times, and is a distance d = 9.4 cm from the lens. What is the focal length (in cm) of the lens? cm i

q37 An object (height = 8.2 cm) and its image are on opposite sides of a converging lens. The object is located 19.0 cm from the lens. The image is located 5.5 cm from the lens. Determine the magnification. Enter the numerical part of your answer to two significant figures. Hint: Remember that the sign of the magnification is significant.
