A physicist's left eye is myopic (i.e., nearsighted). 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

You can argue that a that piece of glass, such as in a window, is like a lens with an infinite focal length. If so, where does it form an image? That is, how are diand dorelated?
The magnification of an upright image that is 34.0 cm away from its object is 0.400. What type of lens is used to form the image, and what is its focal length?
A particular patients eyes are unable to focus on objects closer than 35.0 cm and corrective lenses are to be prescribed so that the patient can focus on objects 20.0 cm from their eyes. (a) Is the patient nearsighted or farsighted? (b) If contact lenses are to lie prescribed, determine the required lens power. (c) If eyeglasses are to be prescribed instead and the distance between the eyes and the lenses is 2.00 cm, determine the power of the required corrective lenses. (d) Are the required lenses converging or diverging?
A 7.5x binocular produces an angular magnification of 7.50, acting like a telescope. (Mirrors are used to make the image upright.) If the binoculars have objective lenses with a 75.0 cm focal length, what is the focal length of the eyepiece lenses?
