To solve the problem of where to place an object in front of a convex lens with a focal length of 40 cm to obtain an image that is double the height of the object, we can follow these steps: ### Step 1: Understand the Magnification The magnification (M) of a lens is given by the formula: \[ M = \frac{V}{U} \] where \( V \) is the image distance and \( U \) is the object distance. Since we want the image to be double the height of the object, we set: \[ M = 2 \] ...
