The equation of a transverse wave traveling along a very long string is y=3.0sin(0.020πx−4.0πt), where x and y are expressed in centimeters and I 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 = 0.26 s?
