A standing wave is described by the wave function where x and y are in meters and t is in seconds. (a) Prepare graphs showing y as a function of x for five instants: t = 0, 5 ms, 10 ms, 15 ms, and 20 ms. (b) From the graph, identify the wavelength of the wave and explain how to do so. (c) From the graph, identify the frequency of the wave and explain how to do so. (d) From the equation, directly identify the wavelength of the wave and explain how to do so.(e) From the equation, directly identify the frequency and explain how to do so.
Why we are showing work done over a closed path is zero to prove that electrostatic forces are conservative
