JEE Main & Advanced Physics Wave Optics / तरंग प्रकाशिकी Question Bank EM Waves

  • question_answer
    If \[\overrightarrow{E}\] and \[\overrightarrow{B}\] are the electric and magnetic field vectors of E.M. waves then the direction of propagation of E.M. wave is along the direction of [CBSE PMT 1992, 2002; DCE 2002, 05]

    A)            \[\overrightarrow{E}\]    

    B)            \[\overrightarrow{B}\]

    C)            \[\overrightarrow{E}\times \overrightarrow{B}\]   

    D)            None of these

    Correct Answer: C

    Solution :

               EM waves travels with perpendicular to E and B. Which are also perpendicular to each other \[\vec{v}=\vec{E}\times \vec{B}\]
