 Title: Superposition of two waves (same frequency, different amplitude, phase/dir ) Post by: Fu-Kwun Hwang on September 29, 2008, 03:41:13 pm The following applet shows the superposotion of two waves.Blue curve represent wave move in x direction: y(t)=A*sin(k*x-w*t);where k=wavelength/(2*pi),  w=period/(2*pi)Green curve represent wave move in +x or -x direction: y(t)=A*sin(k*x-w*t+phi) or y(t)=A2*sin(k*x+w*t+phi) :Click checkboxsame V to select the first one.Cyan curve is the sum of the above two waves. -*- Title: Re: Superposition of two waves (same frequency, different amplitude, phase/dir ) Post by: Jocafis on October 23, 2017, 08:29:35 am Quote from: Fu-Kwun Hwang on September 29, 2008, 03:41:13 pmThe following applet shows the superposotion of two waves.Blue curve represent wave move in x direction: y(t)=A*sin(k*x-w*t);where k=wavelength/(2*pi),  w=period/(2*pi)Green curve represent wave move in +x or -x direction: y(t)=A*sin(k*x-w*t+phi) or y(t)=A2*sin(k*x+w*t+phi) :Click checkboxsame V to select the first one.Cyan curve is the sum of the above two waves. -*-
