Two points on a string are observed as a traveling wave passes them. The points are at x1 = 0 and x2 = 1 m. The transverse motion of the two points are found to be as follows: y1 = 0.2 sin (3*pi*t) y2 = 0.2 sin (3*pi*t + pi/8) What is the frequency (in Hertz), wavelength, speed of the wave, and the direction the wave travels in?
