A standing wave is established in a string and can be described by the equation: y(x, t) = 6.96 sin(22.1x) cos(1110t) cm. Where x is in m and t is in s. Part 1) Write an equation to describe the movement of an increment of string at x = 0.415 m as a function of time. y(t) = Part 2) What is the maximum speed of a piece of string at x = 0.415 m? m/s COS( Umax Part 3) What is the wavelength of this standing wave? 1 Check m cm
