    The dimension of K in the wave equation given by\[y=A\sin \omega \left( \frac{x}{V}-K \right)\]are

    A)  LT                              

    B)  T

    C) \[{{T}^{-1}}\]                                 

    D) \[{{T}^{2}}\] 

    Correct Answer: B

    Solution :

    \[y=A\sin \omega \left( \frac{x}{V}-K \right)\] Clearly, \[\left( \frac{x}{V}-K \right)\]has the dimensions of time. \[\therefore \]K has the dimensions of time (T). Hence, the correction option is [b].
