To practice Tactics Box 18.1 Analyzing refraction. If a ray refracts between medium 1 and medium 2, having indices of refraction n1 and n2, the ray angles θ1 and θ2 in the two media are related by Snell's law, n1sinθ1=n2sinθ2. This law becomes a central idea in a procedure for analyzing refraction problems, as explained in the following Tactics Box. Draw a ray diagram. Represent the light beam with one ray. Draw a line normal to the boundary. Do this...

An incident coherent light ray strikes the interface between two different media with indices of refraction n1 and n2 (see figure below). Part of the ray gets reflected, and part of the ray gets refracted. Based on the information shown in the figure, which of the following is true? Let v1 and v2 be the speed of light in media 1 and 2, respectively. v1 < v2 v1 = v2 The reflected ray undergoes no phase shift relative to the...

A uniform film of TiO2, 1036 nm thick and having index of refraction 2.62, is spread uniformly over the surface of crown glass of refractive index 1.52. Light of wavelength 600 nm falls at normal incidence onto the film from air. You want to increase the thickness of this film so that the reflected light cancels. What is the minimum thickness of TiO2 that you must add so the reflected light cancels as desired? After you make the adjustment in...
