A wave on a string is described by the relation y =0.15 sin(35t -0.025x), where t is measured
in seconds and x in meters. Find the amplitude, frequency, wavelength, and speed of this wave.
Amplitude "0.15(m)"
Frequency "\\nu=\\frac{\\omega}{2\\pi}=\\frac{35}{2\\cdot3.14}=5.57(Hz)"
Wavelength "\\lambda=\\frac{2\\pi}{k}=\\frac{2\\cdot3.14}{0.025}=251.3(m)"
Phase speed "v=\\frac{\\omega}{k}=\\frac{35}{0.025}=1400(m\/s)" or "v=\\lambda\\nu=251.3\\cdot5.57=1400(m\/s)"
