JEE Main & Advanced Physics Wave Mechanics Question Bank Stationary Waves

  • question_answer
    Two waves are approaching each other with a velocity of 16 m/s and frequency n. The distance between two consecutive nodes is                           [CPMT 2001; Pb. PMT 1999]

    A)            \[\frac{16}{n}\]                   

    B)            \[\frac{8}{n}\]

    C)            \[\frac{n}{16}\]                   

    D)            \[\frac{n}{8}\]

    Correct Answer: B

    Solution :

                 Distance between two nodes = \[\frac{\lambda }{2}\] \[=\frac{v}{2n}=\frac{16}{2n}=\frac{8}{n}\]
