  • 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                        [DPMT 1999]

    A)            36.6 m                                     

    B)            40.5 m

    C)            42.3 m                                     

    D)            50.9 m

    Correct Answer: A

    Solution :

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