1. A woman can read the large print in a newspaper only when it is at a distance of 57 cm or more from her eyes. (a) Is she nearsighted (myopic) or farsighted (hyperopic), and what kind of lens is used in her glasses to correct her eyesight? (b) What should be the refractive power (in diopters) of her glasses (worn 2.6 cm from the eyes), so she can read the newspaper at a distance of 24 cm from the eyes?

2. An object is 25 cm in front of a diverging lens that has a focal length of -17 cm. How far in front of the lens should the object be placed so that the size of its image is reduced by a factor of 2.3?

Answer as specific as possible, please!

1. A ray of sunlight is passing from diamond into crown glass; the angle of incidence is 35.00°. The indices of refraction for the blue and red components of the ray are: blue (ndiamond = 2.444, ncrown glass = 1.531), and red (ndiamond = 2.410, ncrown glass = 1.520). Determine the angle between the refracted blue and red rays in the crown glass. 2. An object is 25 cm in front of a diverging lens that has a focal length...

Contact lenses are placed right on the eyeball, so the distance from the eye to an object (or image) is the same as the distance from the lens to that object (or image). A certain person can see distant objects well, but his near point is 50.0 cm from his eyes instead of the usual 25.0 cm . Part A Is this person nearsighted or farsighted? Is this person nearsighted or farsighted? This person is nearsighted. This person is farsighted....

(1)(A)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 22.5 cm from her eyes. Determine the focal length of her glasses for each of the following cases. She wears her eyeglasses 1.80 cm from her eyes. She wears her eyeglasses 2.80 cm from her eyes. (B)What magnification is produced by a 0.150 cm focal length...

Without her glasses, Dr.D.’s myopic eyes can only image objects that are, at most, 18.5cm awayfrom her eye(this is called her “far point”). Her “near point” (the closest she can image an object) is 10.5 cm from her eye. With this range of vision, she obviously needs glasses. Let’s say we want her glasses to allow her to see an object 20 feet away(not really the same as “20/20” vision.... but close enough). You also need to note her glasses...

A pair of glasses is designed for a person with a far-point distance of 4 m so that she can read street signs 19.5 m away. (The far-point distance is the distance from the eye at which you are just able to properly focus a distant object.) (a) If the glasses are to be worn 1.0 cm from her eyes, what is the needed focal length? Answer: -5.02 m (b) Compare this focal length (find the percent difference) to the...
