Standing Wave Formation

Below given animation depicts two waves moving by a medium in opposite directions. The blue wave is moving to the right and the green wave is moving to the left. As is the case in any condition in that two waves meet although moving along the similar medium, interference occurs. The blue wave and the green wave interfere to form a latest wave pattern called as the resultant. The resultant in the animation below is display in black. The resultant is merely the result of the two individual waves - the blue wave & the green wave - added together in accordance along with the principle of superposition.
