The equation of a transverse wave traveling on a string is given by y = 0.5 sin((3 nx/8) - (nt) + n/8), in which x and y are expressed in meters and / is in seconds. The linear mass density of the string is 10 gm/m. (a) What is the displacement at x = 2 m, t = 1s? (b) Find the wavelength and period of the wave. (c) Calculate the transverse velocity of a point on the string at x = 2 m, t = 1s. (d) Determine the velocity of propagation of the wave. (e) What is the tension in the string
