Wave Interference

1. Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium.
2. Wave interference is a phenomenon in which two waves combine by adding their displacement together at every single point in space and time, to form a resultant wave of greater, lower, or the same amplitude.

Interference can be defined as the phenomenon in which two or more waves meet each other and superpose to form a resultant wave than maybe of greater, lower or the same amplitude depending upon the nature of superimposition or alignment of peaks and troughs of the overlapping waves. When two or more waves arrive at the same point while travelling through the same medium, they superimpose themselves on one another or more specifically we can say that, the disturbances of the waves superimpose when they come together. Each of these disturbances corresponds to a force, and we know that forces add. Now if the disturbances are along the same line, then the resulting wave is a simple addition of the disturbances of the individual waves similar two how two forces acting in the same direction add up.Thus,in this case the amplitude of two waves also adds up to give resultant amplitude.
