Step-by-step explanation:
When light passes through a prism, it is bent, or refracted, by the different layers of the prism. This causes the light to separate into its different colors, creating a rainbow. The specific colors that are produced depend on the angle at which the light hits the prism and the index of refraction of the prism material. The index of refraction is a measure of how much the light is bent as it passes through the material. Different materials have different indices of refraction, which can affect the colors that are produced by the prism. For example, a prism made of glass will produce different colors than a prism made of water, because glass and water have different indices of refraction.
