Web19 mei 2024 · I'm trying to understand the connection between the wave equation. (W) ∂ t t u − c 2 Δ u = f. and the Helmholtz equation. (H) Δ U + k 2 U = − 1 c 2 F. I think I have quite a good intuition how the wave equation (W) works: If we stimulate our medium with some f, this "information" is propagated in all directions with a certain velocity c.
