Prof gave us this equation and question: The equation of a transverse wave traveling in a rope is: y=10sin*pi(0.01x-2.00t) He said that x and y are expressed in cm, and time in seconds. We are to: A. find the amplitude, frequency(Hz), velocity(cm) and wavelength(cm) of the wave. B. find the maximum transverse speed of a particle in the rope. I am not sure how to answer these, because I do not know if the amplitude of 10 is in meters or cm. Also, does k=rad/m or rad/cm? I am confused since he specified that x and y are in cm. Does this make everything given in the equation cm? Or is there some standard that keeps them as meters? I know that you cannot read my professors mind. I am hoping there is some sort of standard that applies here, or someones experience can win out over my prof's vagueness. Of course, this is due the next time that class meets (Thursday), so no time to clarify with him. Any help would be great.
