    An LC resonant circuit contains a 400 pF capacitor and a 100 mH inductor. It is set into oscillation coupled to an antenna. The wavelength of the radiated electromagnetic waves is

    A)            377 mm                                  

    B)            377 metre

    C)            377 cm                                    

    D)            3.77 cm

    Correct Answer: B

    Solution :
