The equation of a wave traveling Along the positive \(x\) direction is given by \(y=\) \(0.20 \sin (500 \mathrm{t}\) - 20x).
The amplitude, angular frequency and wavelength of the wave are respectively given by ____________
A. \(0.2 \mathrm{~cm}, 500 \mathrm{rad} / \mathrm{s}, 20 \mathrm{~cm}\)
B. \(0.2 \mathrm{~cm}, 500 \mathrm{rad} / \mathrm{s}, 0.1 \mathrm{\pi cm}\)
C. \(0.2 \mathrm{~cm}, 2 \times 10^{-3} \mathrm{rad} / \mathrm{s}, 0.1 \pi \mathrm{cm}\)
D. \(5 \mathrm{~cm}, 2 \times 10^{-3} \mathrm{rad} / \mathrm{s}, 0.05 \mathrm{~cm}\)
Correct Answer: B
