(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 microscope objective that is 0.155 cm from the object being viewed? what is the overall magnification if an eyepiece that produces a magnification of 8.50✕ is used?

(C)What is the angular magnification of a telescope that has a 124-cm focal length objective and a 2.36-cm focal length eyepiece?

(D)An astronomical telescope has an objective lens with a refractive power of 1.50 D. Determine the refractive power of an eyepiece that will result in the telescope having an angular magnification of −140.
