waves

Question: A plane progressive wave is represented by the equation $y=0.1\sin \left( 200\pi t-\frac{20\pi x}{17} \right)$ where y is displacement in m, t in second and x is distance from a fixed origin in meter. The frequency, wavelength and speed of the wave respectively are



1) 100 Hz, 1.7 m, 170 m/s
2) 150 Hz, 2.4 m, 200 m/s
3) 80 Hz, 1.1 m, 90 m/s
4) 120 Hz, 1.25 m, 207 m/s
