Helmholtz
WebHelmholtz’s equation, named after Hermann von Helmholtz, is used in Physics and Mathematics. It is a partial differential equation and its mathematical formula is: 2 A + k 2 A = 0. Where, 2: L a p l a c i a n. k: wavenumber. A: amplitude. Helmholtz’s equation finds application in Physics problem-solving concepts like seismology, acoustics ... In mathematics, the eigenvalue problem for the Laplace operator is known as the Helmholtz equation.
