wave equation

n

(Physics / General Physics) Physics a partial differential equation describing wave motion. It has the form #X2207;²φ = (1/c²) ✕ (∂²φ/∂t²), where #X2207;² is the Laplace operator, t the time, c the speed of propagation, and φ is a function characterizing the displacement of the wave
