    "Tice splitting of different colours of light in a

    prism is :
    A Reflection of light Correct Answer Incorrect Answer
    B Dispersion light Correct Answer Incorrect Answer
    C Diffraction light Correct Answer Incorrect Answer
    D Refraction of light Correct Answer Incorrect Answer

    Solution

    The refractive index of many materials (such as glass) varies with the wavelength or colour of the light used, a phenomenon known as dispersion. This causes light of different colours to be refracted differently and to leave the prism at different angles,creatinganeffectsimilartoarainbow.In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency, or alternatively when the group velocity depends on the frequency.
