A wave is given by \[y=3\sin 2\pi \left( \frac{t}{0.04}-\frac{x}{0.01} \right)\], where y is in cm. Frequency of wave and maximum acceleration of particle will be [RPET 1997]

• A.            \[100\,Hz,\ 4.7\times {{10}^{3}}\,cm/{{s}^{2}}\]
• B.            \[50\,Hz,\ 7.5\times {{10}^{3}}\,cm/{{s}^{2}}\]
• C.            \[25\,Hz,\ 4.7\times {{10}^{4}}\,cm/{{s}^{2}}\]         
• D.            \[25\,Hz,\ 7.4\times {{10}^{4}}\,cm/{{s}^{2}}\]
