When some force exerted by syatem of charges on a charge then total force experienced by charge is equal to vector sum of indivisual forces F=f1+f2+… F =kq0q1/|r1-r2|+kq0k2/|rn-r0| F=1/4πE0. Q0q/|rn-r|2

Superposition of waves is the process in which two or more different waves travelling through a media simultaneously overlap one another without losing their individual nature and shape. 

Principle of superposition: When two or more waves of the same nature travel past a point simultaneously, the resultant displacement at the point is vector sum of the instantaneous displacements due to individual wave. 

If  are the displacement vectors due to individual waves at a point at a certain instant, then the resultant displacements due to individual wave is given by, 

                    

Some important cases of superposition of waves are:

(i) Stationary waves,
(ii) Beats,
(iii) Interference
