Interference:
Overlaping of two waves is called Interference (or) The phenomenon happends at two or more waves passes through same region at the same time is called Interference .
Interference is 2 types :
1)Constructive Interference
2)Destructive interference
1)Constructive Interference :
When crust of one wave Interference with crust of another wave (or) trough of one wave Interference with trough of another wave is called Constructive Interference .
In Constructive Interference resultant displacement is maximum (y1+y2) .
2)Destructive interference :
When crust of one wave Interference with trough of another wave (or) When trough of one wave Interference with crust of another wave is called Destructive interference .
In Destuctive Interference resultant displacement is minimum (y1-y2)
