For a convex lens following equation describes the relation between the distance from the object to lens, u and the distance between the image and lens v, where f is the focal length of the lens. (a)Draw the equation of the distance between object and its image as a function of u for a lens with the focal lens of f = 1 mm. (b) Find u that is associated with the minimum distance of the object and image for any focal length. %3D Object Image
