    The equation of a wave is represented by \[y={{10}^{-4}}\sin \,\left[ 100\,t-\frac{x}{10} \right].\] The velocity of the wave will be                                                                                        [CBSE PMT 2001]

    A)            100 m/s                                  

    B)            250 m/s

    C)            750 m/s                                  

    D)            1000 m/s

    Correct Answer: D

    Solution :

               \[v=\frac{\omega }{k}=\frac{100}{1/10}=1000\] \[m/s\]
