JEE Main & Advanced Physics Wave Mechanics Question Bank Stationary Waves

  • question_answer
    When a stationary wave is formed then its frequency is [Kerala (Engg.) 2002]

    A)            Same as that of the individual waves

    B)            Twice that of the individual waves

    C)            Half that of the individual waves

    D)            None of the above

    Correct Answer: A

    Solution :

                         If \[{{y}_{incident}}=a\sin (\omega t-kx)\] and \[{{y}_{stationary}}=a\sin (\omega t)\cos kx\]                    then it is clear that frequency of both is same (w)
