Question

    Which colour of light shows maximum deviation when

    passed through a prism?
    A White Correct Answer Incorrect Answer
    B Red Correct Answer Incorrect Answer
    C Violet Correct Answer Incorrect Answer
    D Green Correct Answer Incorrect Answer

    Solution

    The angle of deviation, by which the light of a particular wavelength gets deviated on passing through a medium, depends upon the refractive index of the medium, as encountered by that light wavelength. The smaller the wavelength of the passing light, the greater is the refractive index observed.
