waves

Question: The displacement $y$ (in cm) produced by a simple harmonic wave is $y=\frac{10}{\pi }\sin \left( 2000\pi t-\frac{\pi x}{17} \right)$. The periodic time and maximum velocity of the particles in the medium will respectively be

1) ${{10}^{-3}}$sec and 330 m/sec

2) ${{10}^{-4}}$sec and 20 m/sec

3) ${{10}^{-3}}$sec and 200 m/sec

4) ${{10}^{-2}}$sec and 2000 m/sec
