Please explain me the difference between superposition and interference

Expert Answer:

Interference is the result of superposition of two waves.

In simple terms superposition describes the overlapping of two waves.

When two or more wave trains of light travelling in a medium superimpose(overlap) upon each other , then the resultant displacement at any instant is given by the sum of the displacement due to individual waves.This results in interference.

Thus we can say that interference is the phenomenon of re-distribution of energy in a medium on account of superposition of light waves from two coherent light sources.
