You shine white light onto the edge of a slab of glass, whose edge has been cut at an angle of 55? . If white light enters parallel to the top and bottom surfaces of the glass, and the index of refraction of the glass is nblue = 1.66 at 400 nm and nred = 1.61 at 700 nm, across what angle ?? is the light dispersed inside the glass?

Answer #1

To solve this problem we use Snell`s law of refraction. Knowing the incidence angle and the refraction index of air and glass we can find the refraction angle of blue and red beam. Finally, we find the difference between these two angles in order to solve the problem.

    A beam of white light is incident on the surface of a diamond at an angle θa. (Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. For example, the indices of refraction in diamond are nred=2.410 for red light and nblue=2.450 for blue light. Thus, blue light and red light are refracted at different angles inside the diamond, as shown in...
