The equation of a transverse wave traveling along a very long string is y = 6.0 sin (0.020πx + 4.0πt), where x and y are expressed in centimeters and r is in seconds. Determine
(a) The amplitude,
(b) The wavelength,
(c) The frequency,
(d) The speed,
(e) The direction of propagation of the wave, and
(f) The maximum transverse speed of a particle in the string.
(g) What is the transverse displacement at x = 3.5 cm when t = 0.26s?
