British Dictionary definitions for wave equation

wave equation

noun
1.
(physics) a partial differential equation describing wave motion. It has the form ∇²φ = (1/c²) × (∂²φ/∂t²), where ∇² is the Laplace operator, t the time, c the speed of propagation, and φ is a function characterizing the displacement of the wave
