    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)  speed\[\left( \frac{\lambda }{T} \right)\]

    Correct Answer: D

    Solution :

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