A wave traveling in the +x direction has an amplitude of 0.50 m, a speed of 5.7 m/s, and a frequency of 18 Hz. Write the equation of the wave in the form given by either Equation 16.3 or 16.4. (Answer in terms of t and x. Assume standard units.)
please check my answer:
y= A sin (2pift-2pi(x)/wavelength (formula)
y=.5msin[2pi*18hz)t-(2pi)x/.31667]
correct.
