JEE Main & Advanced Physics Wave Mechanics Question Bank Organ Pipe (Vibration of Air Column)

  • question_answer
    If the temperature increases, then what happens to the frequency of the sound produced by the organ pipe                                                        [RPET 1996; DPMT 2000; RPMT 2001]

    A)            Increases                               

    B)            Decreases

    C)            Unchanged                           

    D)            Not definite

    Correct Answer: A

    Solution :

               Due to rise in temperature, the speed of sound increases. Since \[n=\frac{v}{\lambda }\] and \[\lambda \] remains unchanged, hence n increases.
