Question

    The speed of light with the rise in the temperature of

    the medium :
    A Increases Correct Answer Incorrect Answer
    B Decreases Correct Answer Incorrect Answer
    C Remains unaltered Correct Answer Incorrect Answer
    D Drops suddenly Correct Answer Incorrect Answer

    Solution

    The speed of light with the rise in the temperature of the medium remains unaltered because speed of light doesn't depend on temperature. It does depend, however, on the refractive index of the substance it is travelling through. The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics.
