A plane progressive wave is represented by the equation `y=0.1 sin (200 po t-(20 pi x)/(17))`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
A. `100Hz, 1.7 m, 170 m//s`
B. `150 Hz, 2.4 m, 200 m//s`
C. `80 Hz, 1.1 m , 90 m//s`
D. `120 Hz, 1.25 m, 207 m//s`
