5. A fiber-optic cable (such as those used in endoscopes or other medical equipment) consists of a glass or plastic cylinder called the core surrounded by another layer made out of a different type of glass or plastic called the cladding (see figure below). Cladding (n;) Core (n) a. In order for the light to travel along the length of the fiber, total internal reflection should happen any time the light beam is incident on the core-cladding interface (such as point A). Show that for this condition to be satisfied, the maximum incident angle 0 should be given as sin 0 = n1 1- b. Find this maximum angle if n; = 1.58 and n2 = 1.53. Answer: 23.2° %3! la

What is most likely to happen to a beam of light when it reflects from a shiny metallic surface at an arbitrary angle? Choose the best answer, (a) It is totally absorbed by the surface, (b) It is totally polarized, (c) It is un-polarized. (d) It is partially polarized, (e) More information is required.
Consider a beam of light from the left entering a prism of apex angle as shown in Figure P34.34. Two angles of incidence, 1, and 3, are shown as Hell as two angles of refraction, 2 and 4. Show that = 1 + 3. Figure P34.34
A jellyfish is floating in a water-filled aquarium 1.00 m behind a flat pane of glass 6.00 cm thick and having an index of refraction of 1.50. (a) Where is the image of the jellyfish located? (b) Repeat the problem when the glass is so thin that its thickness can be neglected. (c) How does the thickness of the glass affect the answer to part (a)?
Figure P35.20 (page 958) shows a curved surface separating a material with index of refraction n1 from a material with index n2. The surface forms an image I of object O. The ray shown in red passes through the surface along a radial line. Its angles of incidence and refraction are both zero, so its direction does not change at the surface. For the ray shown in blue, the direction changes according to Snells law, n1 sin 1 = n2 sin 2. For paraxial rays, we assume 1, and 2 are small, so we may write n1 tan 1 = n2 tan 2. The magnification is defined as M = h/h. Prove that the magnification is given by M = n1q/n2p. Figure P35.20
(a) Use the thin-lens equation to derive an expression for q in terms of f and p. (b) Prove that for a real object and a diverging lens, the image must always be virtual. Hint: Set f = |f| and show that q must be less than zero under the given conditions. (c) For a real object and converging lens, what inequality involving p and f must hold if the image is to be real?
