Two waves of the same amplitude and wavelength, travelling in the same direction, are superimposed on each other.[br][list][*]The two interfering waves are [color=#6aa84f]green[/color] and [color=#0000ff]blue[/color]. The [color=#ff0000]red[/color] line shows the resultant.[/*][*]You can change the amplitude of the [color=#0000ff]blue[/color] wave by adjusting the A slider[/*][*] The phase between the two waves can be set between 0° and 360° using the left hand slider.[/*][*]You can pause the animation and set the bottom (time) slider manually.[br][/*][/list]
