An individual is nearsighted; his near point is 12.0 cm and his far point is 42.0 cm. (a) What lens power is needed to correct his nearsightedness? diopters (b) When the lenses are in use, what is this person's near point? X Enter a number is within 10% of the correct value. This may be due to roundoff error, or intermediate results to at least four-digit accuracy to minimize roundoff error. cm

With a near point of 15.0 cm, a nearsighted professor can focus on relatively nearby objects. Yet, with a far point 62.0 cm out, he cannot clearly see distant objects without optical ald. (a) Calculate the focal length (in cm) of a contact lens that would enable this professor to clearly view very distant objects. (Hint: Allow p to approach Infinity in the thin-lens equation). (b) What power (in diopters) describes this contact lens? diopters (c) When this contact lens...

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? (Enter your answer in...

Claudia is nearsighted. She has a near point of 12 cm and a far point of 17 cm. If the corrective lens is 2.0 cm from Claudia’s eye, what lens power will enable her to see distant objects clearly? -6.7 diopters +8.5 diopters -5.3 diopters – 17 diopters

A child's far point is 127 cm and her near point is 12.5 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 1.90 cm from the eye's "thin lens." (1) What is the power, P, of the eye when focused upon the far paint?

With a near point of 12.0 cm, a nearsighted technician can focus on relatively nearby objects. Yet, with a far point 58.0 cm out, he cannot clearly see distant objects without optical aid. (a) Calculate the focal length (in cm) of a contact lens that would enable this technician to clearly view very distant objects. (Hint: Allow p to approach infinity in the thin-lens equation). (b) What power (in diopters) describes this contact lens? (c) When this contact lens is...

(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...

A certain child's near point is 15.0 cm; her far point (with eyes relaxed) is 129 cm. Each eye lens is 2.00 cm from the retina. (a) Between what limits, measured in diopters, does the power of this lens-cornea combination vary? lower bound diopters upper bound diopters (6) Calculate the power of the eyeglass lens the child should use for relaxed distance vision. diopters Is the lens converging or diverging? O converging diverging
