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 \( m, t \)
\( \mathrm{P} \) in second and \( x \) is distance from a fixed origin in meter.

W The frequency, wavelength and speed of the wave respectively are

(a) \( 100 \mathrm{~Hz}, 1.7 \mathrm{~m}, 170 \mathrm{~m} / \mathrm{s} \)
(b) \( 150 \mathrm{~Hz}, 2.4 \mathrm{~m}, 200 \mathrm{~m} / \mathrm{s} \)
(c) \( 80 \mathrm{~Hz}, 1.1 \mathrm{~m}, 90 \mathrm{~m} / \mathrm{s} \)
(d) \( 120 \mathrm{~Hz}, 1.25 \mathrm{~m}, 207 \mathrm{~m} / \mathrm{s} \)
