Transverse waves on a string have wave speed , amplitude , and wavelength . The waves travel in the -x direction, andat the end of the string has its maximum upwarddisplacement. Find the frequency of these waves.Find the wave number of these waves. Write a wave function describing the wave butExpress your answer in terms of the variables x and t .Find the transverse displacement of a particle at x=0.360 m at time t = 0.0150 s.
