    Light wave is travelling along y-direction. If the corresponding \[\vec{E}\] vector at any time is along the x-axis, the direction of \[\vec{B}\] vector at that time is along [UPSEAT 2005]

    A)            y-axis

    B)            x-axis

    C)            + z-axis

    D)            ? z axis

    Correct Answer: D

    Solution :
