1. The waveform of a pulse moving along the x-axis with a speed of 10.0 m/s in the positive x-direction is y(x. 0) = (0.200 m)ex. (a) Draw a graph of the pulse at t = 0. Use a vertical scale of 0.0200 m per grid block and a horizontal scale of 0.200 m per grid block. Graph about 10 points using both negative and positive values of x. (b) Write the wave function y(x, t) for the pulse. * = (0.200)e - ( * - 10 0 + )2 (c) Draw a graph of the pulse at t = 0.300 s. Use the same scale you used in part (a)
