The phenomenon in which two or more waves superpose to form a resultant wave of greater, lower or the same amplitude.
The interference of waves can be witnessed when two waves travel along with the same medium.
Interference is this superposition of lights coming from multiple sources.
There are two types of interference: 4.1 Constructive interference: When two waves travel in the same direction and are in phase with each other, their amplitude gets added, and the resultant wave is obtained. Here, the waves are said to have undergone constructive interference. 4.2 Destructive interference: This kind of wave interference takes place in any location along with the medium when the two waves that interfere with each other have a displacement in the opposite direction.
