 Title: Superposition of pulses Post by: Fu-Kwun Hwang on January 29, 2004, 07:49:58 pm Suppose that there is a pulse moves to the right.    There is a upward transverse motion along the leading edge of the pulse.    The transverse motion vanishes at the peak, and there is downward transverse motion along the trailing edge .Let us consider the superposition of two pulses of identical shape moving relative to each other.Usage :1. Click right mouse to toggle the animation.When the animation stops. The blue curves show the current pulses.  while those red curves show the pulse at the next time interval.Those red arrows indicate the relative motion of pulses. Blue arrows are moving directions of those pulses.For transverse wave blue arrow and red arrow are perpendicular to each other. 2. Click right mouse button twice quickly will reset all the parameters.Even though the wave is flatfor a brief moment, It is not at rest(Think about the velocity at each point, y=0 does not mean Vy=0!).You are welcomed to check out related simulation at Superposition of two impulses (Gaussian wave)  (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=935.0) Title: Re: Superposition of pulses Post by: franklin.christensen on March 06, 2012, 07:21:59 pm Your articles help a lot to the student.I've learn a lot from your  blogs the information is very informative .Itâ€™s like this universal truth that you can not argue with the truth is not universal everything has its exception.Thanks for this information.Thanks for sharing.-*- Title: Re: Superposition of pulses Post by: ericaclayton453 on September 17, 2015, 01:40:49 pm Superimposition is the most important topics in science.
