The WKB approximation, short for Wentzel-Kramers-Brillouin approximation, is a method used in quantum mechanics to find approximate solutions to the Schrödinger equation in situations where the potential varies slowly. It provides a way to analyze quantum tunneling and wavefunction behavior in semi-classical contexts, bridging classical and quantum mechanics by allowing for the analysis of wavefunctions in terms of classical paths.
congrats on reading the definition of WKB approximation. now let's actually learn it.
