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, yellow, green, and blue light refract from the slanted face of the prism into the surrounding material. (Express your answer to 4 significant
