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 h_o = 3.5 cm is placed at a distance of d_o = 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?

d_i = ______

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 = ______
