Superposition of waves
- Superposition of waves is defined as the resultant displacement produced by a number of waves is the vector sum of displacements produced by each of them.
- Two 2 different waves add up to form a single wave and whose displacement will be given by vector sum of individual waves.
- There are 2 types of superposition:-
- Constructive overlap:-When two waves overlap to produce a bigger wave that is known as constructive overlap.
- Either two crests or two troughs overlap to form a bigger wave.
- For constructive overlap both the waves are in phase with each other.
Destructive overlap:-There will no resultant wave when 2 out of phase waves overlap together.
