Superposition of waves
Overlap of two waves at a point in space
Principle of superposition (of waves)
When two waves meet at a point the resultant displacement at that point is equal to the sum of the displacements of the individual waves.
Constructive interference
Superposition of two waves in phase so that the resultant wave has greater amplitude than the original waves
Destructive interference
Superposition of two waves in antiphase so that the waves cancel each other out and the resultant wave has smaller amplitude than the original waves
