    The equation\[y=A\sin 2\pi \left( \frac{t}{T}-\frac{x}{\lambda } \right),\]where the symbols carry the usual meaning and A, T and \[\lambda \]are positive, represents a wave of:

    A)  amplitude 2 A

    B)  period\[T/\lambda \]

    C)  speed \[x\lambda \]

    D)  velocity in negative\[x-\]direction

    E)  speed\[(\lambda /T)\]

    Correct Answer: E

    Solution :

    Speed\[v=\frac{\omega }{k}=\frac{2\pi \times \lambda }{T\times 2\lambda }=\frac{\lambda }{T}\]
