Order the waves by their phase velocity starting with the lowest velocity ranked (1). d(x,t) = (2.0 m)*sin([25/m]x - [1.2/s]t) A transverse wave of amplitude 4.80 m, wavelength 36.75 m and angular frequency 0.0012 rad/s propagating in the positive x direction. A longitudinal wave of amplitude 5 mm, wavelength 3.75 m and period 4.90 s propagating in the negative x direction. d(x,t) = (3.7 m)*sin([4/m]x)*cos([0.12/s]t) d(x,t) = (5.6 mm)*sin([(2*pi)/(3.0 m)]x - [(2*pi)/(0.00036 s)]t) d(x,t) = (0.05 m)*cos([0.48/m]x + [5.2/s]t)
