A person is to be fitted with bifocals. She can see clearly when the object is between 30 cm and 1.5 m from the eye. (a) The upper portions of the bifocals (Fig. P25.16) should be designed to enable her to see distant objects clearly. What power should they have? (b) The lower portions of the bifocals should enable her to see objects located 25 cm in front of the eye. What power should they have?
Endoscopes are medical instruments used to examinethe gastrointestinal tract and other cavities inside the body.The light required for examination is conducted from an outsidesource along a long, flexible bundle of optical fibers tothe tip, where it exits and illuminates the internal cavity. A lenson the tip collects an image of the lighted cavity and anotherfiber bundle conducts the image back along the endoscopeto an eyepiece for viewing (Fig. P22.52). If each fiber in thebundle has diameter d = 1.00 x 10-4 m and refractive indexn = 1.40, find the smallest outside radius R permitted for abend in the fiber if no light is to escape.
