A transverse wave on a string is described by the wave function y(x, t) = 0.322 sin(1.90x + 86.21\") where x and y are in meters and t is in seconds. Consider the element of the string at X = 0. (a) What is the time interval between the first two instants when this element has a position of y = 0.175 m? _x ms (b) What distance does the wave travel during the time interval found in part (a)? _xm
