A ray of yellow light crosses the boundary between glass and air, going from the glass into air. If the angle of incidence is 25°, what is the angle of refraction? (Assume that the index of refraction of glass is 1.5.)
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...
