1. [-/1 Points] DETAILS MY NOTES SERCP11 25.1.P.003. ASK YOUR TEACHER PRACTICE ANOTHER An f/3.00 CCD camera has a 108 mm focal length lens and can focus on objects from infinity to as near as 32.5 cm from the lens. Note: "f/3.00" means "an f-number of 3.00." (a) Apply the definition of f~-number. (b)-(c) Apply the thin-lens equation. The lens must place the object's image on the CCD sensor. Click the hint button again to remove this hint. (a) Determine the camera's aperture diameter in mm. mm Determine the minimum and maximum distances in cm from the CCD sensor over which the lens must be able to travel during focusing. (b) minimum cm ! (c) maximum cm 2. [-/1 Points] DETAILS MY NOTES SERCP11 25.2.P.010.

(O nearsighted () farsighted (b) If the eye-lens distance is 1.99 cm, what is the minimum object distance p from the lens? (Give your answer to at least three significant digits.) cm \\ (c) What image position with respect to the lens will allow the patient to see the object? (Give your answer to at least three significant digits.) cm (d) Is the image real or virtual? Is the image distance g positive or negative? (Select all that apply.) O real image () virtual image () distance is positive () distance is negative (e) Calculate the required focal length. 1 cm (f) Find the power of the lens in diopters.

ASK YOUR TEACHER PRACTICE ANOTHER A person with a nearsighted eye has near and far points of 14 cm and 35 cm, respectively. (a) Assuming a lens is placed 2.0 cm from the eye, what power must the lens have to correct this condition? _\\| diopters (b) Suppose contact lenses placed directly on the cornea are used to correct the person's eye. What is the power of the lens required in this case, and what is the new near point? Hint: The contact lens and the eyeglass lens require slightly different powers because they are at different distances from the eye. P = [ }diopters new near point = [:] cm Need Help? [[Rssaw]] Submit Answer 6. [-/1 Points] DETAILS MY NOTES SERCP11 25.A.P.065.MI. ASK YOUR TEACHER PRACTICE ANOTHER A cataract-impaired lens in an eye may be surgically removed and replaced by a manufactured lens. The focal length required for the new lens is determined by the lens-to-retina distance, which is measured by a sonarlike device, and by the requirement that the implant provide for correct distant vision. (a) If the distance from lens to retina is 23.6 mm, calculate the power of the implanted lens in diopters. ( ] diopters (b) Since there is no accommodation and the implant allows for correct distance vision, a corrective lens for close work or reading must be used. Assume a reading distance of 34.0 cm, and calculate the power of the lens in the reading glasses. ( ] diopters ' | N
