As shown in the figure, white light enters a 45-90-45 crown glass prism at the vertical face. Part of this light refracts at the slanted face into the surrounding material and the rest experiences total internal reflection and exits the prism at the horizontal base. The colors of light that emerge from the slanted face may be chosen by varying the index of refraction of the material surrounding the prism. Determine the required index of refraction of the surrounding material for each of the following cases. (a) Only red, orange and yellow light refract from the slanted face of the prism into the surrounding material. (Express your answer to 4 significant figures.) (b) All colors except violet, blue, and green light refract from the slanted face of the prism into the surrounding material. (Express your answer to 4 significant figures.) The table below shows the different colors of light, their wavelength in a vacuum, and the index of refraction in crown glass.

Light enters a prism of crown glass and refracts at an angle of 5.00 with respect to the normal at the interface. The crown glass has a mean index of refraction of 1.51. It is combined with one flint glass prism (n = 1.65) to produce no net deviation. a. Find the apex angle of the flint glass. b. Assume the index of refraction for violet light (v = 430 nm) is nv = 1.528 and the index of refraction for red light (r = 768 nm) is nr = 1.511 for crown glass. For flint glass using the same wavelengths, nv = 1.665 and nr = 1.645. Find the net dispersion.
