... The wave equation is linear (no ψ 2 (x, t) or any of its derivatives) and therefore if ψ1 and ψ2 are solutions to the equation, then ψ = A1 ψ1 + A2 ψ2 is also a solution, with A1 , A2 arbitrary constants. This is the same principle of superposition which appears in Maxwell’s equations (which are als ...
