Briefly explain the concept of super position principle.

1.	Briefly explain the concept of super position principle.
Answer» Solution :When two or more waves in a medium overlap., their TOTAL displacement is the VECTOR sum of individual displacements. Let us consider two fucntions which CHARACTERIZE the displacement of the waves, for example, `y_(1)=a sin (kx- omegat)` and `y_(2)=A_(2)cos(kx- omegat)` SINCE both `y_(1) and y_(2)` satisfy the wave equation (solutions of wave equation) then their algebraic sum `y=y_(1)+y_(2)` also satisfies the wave equation. It is meant that, the displacement are additive.
