15.44 • The wave function of a standing wave is y(x, t) = 4.44 mm * sin[(32.5rad / m) * x] * sin[(754rad / s) * t] . For the two travel ing waves that make up this standing wave, find the (a) amplitude; (b) wavelength; (c) frequency; (d) wave speed; (e) wave functions. (f) From the information given, can you determine which har monic this is? Explain.
