This eye can see clearly only out to a distance of 27 cm, making it difficult forthe physicist to see a distant apparatus clealy.Determine the focal length f and power P of a lens that will correct this myopia when worn 2.0 cm in front of the eye.f =Is this a converging or a diverging lens?convergingdivergingcmP =diopters

Suppose the telescope is in focus with an eyepiece giving a magnification of 20.3. By what distance must the eyepiece be adjusted when the eyepiece is replaced, with a resulting magnification of 1.0 ✕ 102? Must the eyepiece be adjusted backward or forward? Assume the objective lens has a focal length of 2.32 m. (Use a positive value if the eyepiece must be moved forward toward the objective lens and negative values if the eyepiece must be moved backwards.) cm

Molly has a near point at 45 cm and requires eyeglasses to correct her vision. - What should be the prescription (i.e. the lens power) for her eye? Note: Corrective lenses are available in increments in power of 0.25 diopters, e.g. +1.0, +1.25, +1. 50,...,etc. (Answer must be divisible by 0.25 and the lenses should have the lowest power for which the new near point with the lens is no further than 25 cm) - A 9.0 mm base curve (i.e. radius of curvature) will best fit her cornea. Using the material with index of refractive 1.422, what should be the radius of curvature for the other side of the lens? - What is the new far point after wearing the contact lens.
