JEE Main & Advanced Physics Wave Optics / तरंग प्रकाशिकी Question Bank Doppler's Effect of Light

  • question_answer
    Doppler's effect in sound in addition to relative velocity between source and observer, also depends while source and observer or both are moving. Doppler Effect in light depend only on the relative velocity of source and observer. The reason of this is                                                  [MP PET/PMT 1988]

    A)            Einstein mass - energy relation

    B)            Einstein theory of relativity

    C)            Photoelectric effect

    D)            None of these

    Correct Answer: B

    Solution :

               With reference to this theory the velocity of the observer is neglected w.r.t. the light velocity.
