A light ray in the core (n=1.40) of a cylindrical optical fiber is incident on the cladding. A ray is transmitted through the cladding (n= 1.20) and into the air. The emerging ray makes an angle 02 = 6.10° with the outside surface of the cladding. What angle 01 did the ray in the core make with the axis? Air

White light enters flint glass from air (n₁ = 1). The angle of incidence is 8, = 63 degrees. Due to dispersion in the glass, the index of refraction for red light is 1.662, while the index for violet light is 1.698. Due to this difference, the violet and red parts of white light are refracted by different amounts. What is the difference in refraction angle (AO) between violet and red fin this situation? A0 = degrees n₁ n₂ refracted rays

A light ray traveling in water is incident upon a transparent medium. The angle of incidence is 45.0°, and the transmitted ray is refracted at an angle of 20.0°. What is the speed of light in the transparent medium (in m/s)? X What is the index of refraction of the transparent medium? How is it related to the speed of light in vacuum and the speed of light in the medium? m/s

Problem 13: A ray of light is incident on an air/water interface. The ray makes an angle of 01 = 22 degrees with respect to the normal of the surface. The index of the air is n = 1 while water is n₂ = 1.33. Part (b) Numerically, what is the angle in degrees? 0₂=1 Part (a) Choose an expression for the angle (relative to the normal to the surface) for the ray in the water, 02.

In the figure, light is incident at angle 8₁ = 39° on a boundary between two transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n₁ = 1.28, n₂ = 1.38, n3 = 1.34 and n4 = 1.45, what is the value of (a) 05 and (b) 04? 18₁ Air m n₂ 173 na
