Solution

Light of different colours is deviated at different angles by prism because different colors of light have different wavelengths.
Due to different wavelengths, they travel through the glass at different speeds.
Hence glass offers a different refractive index for different colors.
Hence, the light of different colors is deviated through different angles by a prism
