JEE Main & Advanced Physics EM Waves Question Bank Self Evaluation Test - Electromagnetic Waves

  • question_answer
    If a source is transmitting electromagnetic wave of frequency \[8.2\times {{10}^{6}}Hz,\] then wavelength of the electromagnetic waves transmitted from the source will be

    A) \[36.6\,m\]

    B) \[40.5\,m\]

    C) \[42.3\,m\]

    D) \[50.9\,m\]

    Correct Answer: A

    Solution :

    [a] \[\lambda =\frac{c}{v}=\frac{3\times {{10}^{8}}}{8.2\times {{10}^{6}}}=36.5m\]
