  • question_answer
    The equation of a wave is\[y=2\sin \pi (0.5x-200t)\], where x and y are expressed in cm and t in sec. The wave velocity is [MP PMT 1986]

    A)            100 cm/sec                            

    B)            200 cm/sec

    C)            300 cm/sec                            

    D)            400 cm/sec

    Correct Answer: D

    Solution :

                       Comparing given equation with standard equation of progressive wave. The velocity of wave            \[v=\frac{\omega \,(\text{Co-efficient of }t\text{)}}{k\,(\text{Co-efficient of }x)}=\frac{200\pi }{0.5\pi }=400\,cm/s\]
