A vibrating string creates a harmonic wave of the form y(x, t) = A cos (2 x - wt + 0), where y is the vertical displacement of the string at position x and time t. The figure below shows the wave as a function of time at a fixed position of the string x=0.463 m. The wave propagates with speed v = 252.22 m/s. y (mm) 2 N -2 2 4 t (ms) Find the wavelength of this wave.
