Question: An optic fiber of index of refraction of 1 6 is
An optic fiber of index of refraction of 1.6 is surrounded by a layer called the cladding layer. The index of refraction of the cladding is 1.3. If the angle of incidence inside the fiber is 40°, will there be light leaking into air? What if the angle of incidence is 50°?
Answer to relevant QuestionsTwo people stand 5.0 m apart and 3.0 m away from a large plane mirror in a dark room. At what angle of incidence should one of them shine a flashlight on the mirror so that the reflected beam directly strikes the other ...When you open your eyes underwater, everything is blurry. However, when you wear goggles, you can see clearly. Explain. (a) A10-cm-tall mirror bears the following advertisement: “Full-view mini mirror. See your full body in 10 cm.” How can this be? (b) A popular novelty item consists of a concave mirror with a ball suspended at or ...Use the mirror equation and the magnification factor to show that when do = R = 2f for a concave mirror, the image is real, inverted, and the same size as the object. The image of an object located 30 cm from a mirror is formed on a screen located 20 cm from the mirror. (a) The mirror is (1) convex, (2) concave, (3) flat. Explain. (b) What is the mirror’s radius of curvature?
