An object is located `20 cm` to the left of a converging lens with `f=10 cm.` A second identical lens is placed to the right of the first lens and then moved until the image it produces is identical in size and orientiation to the object. What is the separation between the lenses?

To solve the problem step by step, we will use the lens formula and the properties of lenses. ### Step 1: Understand the setup We have a converging lens with a focal length (f) of 10 cm. An object is placed 20 cm to the left of this lens. We need to find the separation between this lens and a second identical lens placed to the right of the first lens, such that the image produced by the second lens is identical in size and orientation to the object. ### Step 2: Use the lens formula The lens formula is given by: \[ ...
