The equation of a wave travelling along positive x-direction is given by y = 0.20sin(500t - 20x). The amplitude, angular frequency and wavelength of the wave are respectively given by

• A.0.2cm, 500rad/s, 20cm
• B.0.2cm, 500rad/s, 0.1π cm
• C.0.2cm, 2 x 10^-3 rad/s, 0.1πcm
• D.5cm, 2 x 10^-3, 0.05cm
