The principle of superposition in wave motion states that
Answer: A
The principle states that the net displacement is the vector sum of individual displacements.
When two or more waves overlap, the resultant displacement at any point and instant is the (vector) sum of the displacements each wave would cause on its own. It holds for all linear waves, travelling or standing, sound or light.
Waves pass through each other and occupy the same space; interference redistributes energy rather than destroying it; and the principle is not limited to sound or standing waves.
