wave equation

n
(General Physics) 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

The equation (3) is a parametric form, thus we get the general solution of d'Alembert's equation as a parametric representation x = f(p).
D'Alembert's equations of the field show that this speed is equal to the velocity of light corrected by gravitational potential.
