Definition of superposition principle in English English dictionary
The principle that a linear combination of two or more solutions of an equation is itself a solution; it is a feature of many physical laws
A principle holding that certain waves or functions can add together when overlapped to form a new wave or function and then return to their original states when separated
the displacement of any point due to the superposition of wave systems is equal to the sum of the displacements of the individual waves at that point; "the principle of superposition is the basis of the wave theory of light"
