Classical wave function
WebApr 13, 2016 · 3. A "wave function" is a mathematical model (or representation) of a given wave. A "function" is represented by the symbol f. It can be a function of distance (x), time (t), space (r), etc. and is usually represented by an equation. If the equation represents a wave, then the function is a wave function. WebMadelung showed how the complex Schrödinger equation can be rewritten in terms of two real equations, one for the phase and one for the amplitude of the complex wave function, where both equations are not independent of each other, but coupled. Although these equations formally look like classical hydrodynamic equations, they contain all the …

Webequation is of the classical form ∂2Φ ∂t2 = c2 ∂2Φ ∂x2 (1.1) It is easy to verify by direct substitution that the most general solution of the one dimensional wave equation (1.1) is where F and g are arbitrary functions of their arguments. In the x,t (space,time) plane F(x − ct) is constant along the straight line x − ct = constant.
