The true far point should be infinity, so we are taking objects from that distance and focusing them at 4.50 m
Apply 1/f = 1/p + 1/q
1/f = 1/-4.5
f = -4.5 m
Now, for the new near point...
1/-4.5 = 1/.24 + 1/q
q = -22.8
Thus the new near point is 22.8 cm
A nearsighted student wears contact lenses to correct for a far point that is 4.50m from...
The far point of a nearsighted person is 6.9 m from her eyes, and she wears contacts that enable her to see distant objects clearly. A tree is 14.8 m away and 2.8 m high. (a) When she looks through the contacts at the tree, what is its image distance? (b) How high is the image formed by the contacts?
The far point of a nearsighted person is 4.9 m from her eyes, and she wears contacts that enable her to see distant objects clearly. A tree is 23.1 m away and 1.6 m high. (a) When she looks through the contacts at the tree, what is its image distance? (b) How high is the image formed by the contacts?
A nearsighted person wears contact lenses of refractive power -6.0 D. What is her far point? 17 cm 6.0 cm -17 cm -4.0 cm -6.0 cm
A nearsighted person has a far point of 21.5cm and is prescribed contact lenses to correct her vision. What lens strength (a.k.a., lens power), in Diopters, should be prescribed? Give your answer using the usual convention of positive values for converging lenses and negative values for diverging lenses. Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 146, 5.23e-8
People commonly use contact lenses to correct their vision. A patient has a near point of 150 cm and, to correct this, wears contact lenses with a focal length of 50 cm Part A What is the refractive power of her contact lenses? Part B How close can she hold a newspaper and still read it while wearing her contact lenses? Part C The indices of refraction for her contact lens, cornea, and the fluid behind her cornea are 1.6,...
(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...
1. Susan is quite nearsighted; without her glasses, her far point is 52 cm and her near point is 16 cm. Her glasses allow her to view distant objects with her eye relaxed. (a) Are the lenses of her glasses converging or diverging? (b) Find the focal length of the lenses of her glasses. (c) Find her near point while wearing her glasses. (d) Find the minimum power of the lens she should use as a magnifier in order to...
Your physics study partner is nearsighted. She has a near point of 50.0 cm from her eyes and she wears eyeglasses designed to allow her to read a newspaper held at a distance of 20.0 cm from her eyes. Determine the focal length of her glasses for each of the following cases. (a) She wears her eyeglasses 1.80 cm from her eyes. cm (b) She wears her eyeglasses 2.80 cm from her eyes. cm
Velma is extremely nearsighted, and has difficulty seeing anything which is further away than 1.5 meters from her face if she isn't wearing her glasses. Dexter also wears glasses, which correct his farsightedness; he can only see objects clearly when they are more than 50 cm from his eyes. Assuming that each of them wears glasses which are 1.5 cm from their eyes, and that a person with normal vision has a near point of 25 cm and a far...
An individual is nearsighted; his near point is 13.0 cm and his far point is 46.0 cm. (a) What lens power is needed to correct his nearsightedness? in diopters (b) When the lenses are in use, what is this person's near point? in cm
