Question: Suppose the distance from the lens system of the eye (cornea +lens) to the retina is 13 mm.
(a) What must the power of the lens be whenlooking at distant objects? D
(b) What must the power of the lens be when looking at an object20.0 cm from the eye? D
(c) Suppose that the eye is farsighted; the person cannot seeclearly objects that are closer than 1.0m. Find the power of the contact lens you would prescribe so thatobjects as close as 20.0 cm can be seenclearly. D
