Your lab partner is reading information written on the whiteboard in letters that are 4.50 cm high. Her lens-to-retina distance is 1.59 cm and her eyes have a refractive power of 63.1 D.Determine the following.
(a) The distance of the whiteboard from her eyes.
How are the refractive power of a lens and the object and image
distance related? For this case how is the image distance related
to the lens-to-retina distance? m
(b) The size of the image on her retina (include the proper
algebraic sign).

A farsighted man uses contact lenses with a refractive power of 2.20 diopters. Wearing the contacts, he is able to read books held no closer than 0.285 m from his eyes. He would like a prescription for eyeglasses to serve the same purpose. What is the correct prescription for the eyeglasses if the distance from the eyeglasses to his eyes is 0.030 m? in dipoters ??? not 1.67 A diverging lens (f1 = −13.5 cm) is located 23.0 cm to...

an older person needs a pair of reading glasses.Her near point is at 48 cm from her eyes and reading glasses are 2 cm from her eyes. The glasses should allow her to read 25 cm away. What are the object and image distances? what is the magnification of these lenses? What is the focal length of the pair of glasses? What is the optical power of the lens pair? What type of lenses (converging, diverging) does she need?

(1.) Nearsightedness (a.) A nearsighted person has a far point that is 323 cm from her eye. Her lens in a pair of glasses is 2 cm in front of her eye. What focal length is required to cast the image of a far-away object at her far point? (b.) If these glasses are used to view an object 525 cm from her eye, where do her glasses cast the image? In both cases, quote your distance as measured from...

Your lab partner makes another mistake and records the position of an image and object in front of a lens with a few rays included as shown. However, your lab partner forgets to record whether A or B is the superpowers to figure out from the figure what is the proper description:

A child's far point is 129 cm and her near point is 15.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the child's eyes are identical, with each retina lying 1.80 cm from the eye's "thin lens." (a) What is the power, P, of the eye when focused upon the far point?
