Question

Please solve problem not just solutions A patient can't see objects closer than 39.3 cm and wishes to clearly see objects that are 18.4 cm from his eye. (a) Is the patient nearsighted or farsighted? nearsighted farsighted (b) If the eye-lens distance is 2.03 cm, what is the minimum object distance p from the lens? cm (c) What image position with respect to the lens will allow the patient to see the object? cm (d) Is the image real or virtual? Is the image distance q positive or negative? virtual image real image distance is negative distance is positive (e) Calculate the required focal length. cm (f) Find the power of the lens in diopters. diopters (g) If a contact lens is to be prescribed instead, find p, q, and f, and the power of the lens. p = cm q = cm f = cm P = diopters

Explanation / Answer

a) The patient is nearsighted d) image is virtual e) 1/f = 1/v +1/u f) power = 1/f
