A sinusoidal wave in a string is explained by the wave function y = (0.06m) sin (4.4x - 7.0t) where x and y are in meters and t is in seconds. (a) In what direction does the wave travel and what is its speed? (b) Discover the wavelength, frequency, and period of the wave. (c) What is the maximum speed of any short string segment? (d) What is the maximum displacement of any string segment?
