Transverse waves on a string have wave speed amplitude 0.0700 m, and wavelength 0.320 m. the waves travel in the and at the end of the string has its maximum upward displacement. (a) find the frequency, period, and wave number of these waves. (b) write a wave function describing the wave. (c) find the transverse displacement of a particle at at time (d) how much time must elapse from the instant in part (c) until the particle at next has maximum upward displacement?
