G1 Physics · Accepted Answer

For visible light: λ(red) > λ(yellow) > λ(violet) A longer wavelength undergoes less deviation in a prism. Therefore, red light bends less than yellow and violet light. Also, in a dispersive medium, refractive index depends on wavelength. Hence, both statements are true.
