Calculate the: a) focal length, and b) Lens Power, of corrective optics (glasses) that you should get for her at the drug store so that objects placed at the normal near point (25 cm) will be in focus. Assume that both eyes need the same correction and that the lenses will be placed 2 cm in front of her eyes. (Hint: for an object placed at the normal near point, the lens must form an image of the object at her near point).24) A transparent photographic slide is placed in front of a converging lens with a focal length of 2.60 cm .
