Chapter 34, Problem 31P
An optical fiber has an index of refraction n and diameter d. It is surrounded by vacuum. Light is sent into the fiber along its axis as shown in Figure P34.31. (a) Find the smallest outside radius Rmin permitted for a bend in the fiber if no light is to escape. (b) What If? What result does part (a) predict as d approaches zero? Is this behavior reasonable? Explain. (c) As n increases? (d) As n approaches 1? (c) Evaluate Rmin assuming the fiber diameter is 100 μm and its index of refraction is 1.40.

Q.1 A light ray is reflected from a mirror with an angle 60.0° to the normal. What was the angle
of incidence?
Q.2 Light passes through a transparent substance at a speed of 2 ×108 m/s. What is the index of

Q.3 The wavelength of a monochromatic light source is measured to be 5.5 × 10-8 m in a diffraction
experiment. (a) What is the frequency? (b) What is the energy of a photon of this light?
Your answer is partially correct.
The figure shows an optical fiber in which a central plastic core of index of refraction n, = 1.60 is surrounded by a plastic sheath of
index of refraction n2 = 1.52. Light can travel along different paths within the central core, leading to different travel times through the
fiber. This causes an initially short pulse of light to spread as it travels along the fiber, resulting in information loss. Consider light that
travels directly along the central axis of the fiber and light that is repeatedly reflected at the critical angle along the core-sheath
interface, reflecting from side to side as it travels down the central core. If the fiber length is 370 m, what is the difference in the travel
times along these two routes?

- How many times will the incident beam in Figure P34.33 (page 922) be reflected by each of the parallel mirrors? Figure P34.33arrow_forwardFigure P23.28 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 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.
