An artificial lens is implanted in a person's eye to replace a diseased lens. The distance between the artificial lens and the retina is2.82cm. In the absence of the lens, an image of a distant object (formed by refraction at the cornea) falls5.81cm behind where the implanted lens would be inserted. The lens is designed to put the image of the distant object on the retina. What is the power of the implanted lens?Hint:Consider the image formed by the cornea to be a virtual object.
