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

  • question_answer
    The oscillating electric and magnetic vectors of an electromagnetic wave are oriented along [CBSE PMT 1994]

    A)            The same direction but differ in phase by 90°

    B)            The same direction and are in phase

    C)            Mutually perpendicular directions and are in phase

    D)            Mutually perpendicular directions and differ in phase by 90°

    Correct Answer: C

    Solution :

               \[\vec{E}\] and \[\vec{B}\] are mutually perpendicular to each other and are in phase i.e. they become zero and minimum at the same place and at the same time.
