7-2 The equation of a transverse wave traveling along a string is given by y = 0.3 sin 1r(0.5x - 50:), where y and x are in centimeters and t is in seconds. (a) Find the amplitude, wavelength, wave number, frequency, period, and velocity of the tirave. (b) Find the maximum transverse speed of any particle in the string
