중첩원리,superposition_principle

수학의 중첩원리랑 물리의 것이랑 차이가 있나?

This principle applies to any 선형계,linear_system

Additivity $F(x_1+x_2)=F(x_1)+F(x_2)$
Homogeneity $F(ax)=aF(x)$
(a: 스칼라,scalar)

From Serway Physics

물리에서 파동,wave의 중첩원리란..

If two or more traveling waves are moving through a medium, the resultant vaule of the wave function at any point is the algebraic sum of the values of the wave functions of the individual waves.

Waves that obey this principle are called linear waves.
