noun Physics.

- the wave equation of nonrelativistic quantum mechanics.Also called Schrödinger wave equation.Compare wave equation(def 2).

noun

- an equation used in wave mechanics to describe a physical system. For a particle of mass m and potential energy V it is written (i h /2π).(∂ψ/∂ t) = (– h ²/8π² m)∇²ψ + Vψ, where i = √–1, h is the Planck constant, t the time, ∇² the Laplace operator, and ψ the wave function
