WebbAnswer. The Schrödinger equation (also known as Schrödinger’s wave equation) is a partial differential equation that uses the wave function to describe the dynamics of quantum … WebbAbstract. After formulating the pressure wave equation in half-space minus a crack with a zero Neumann condition on the top plane, we introduce a related inverse problem. That inverse problem consists of identifying the crack and the unknown forcing term on that crack from overdetermined boundary data on a relatively open set of the top plane. For an incident wave traveling from one medium (where the wave speed is c1) to another medium (where the wave speed is c2), one part of the wave will transmit into the second medium, while another part reflects back into the other direction and stays in the first medium. The amplitude of the transmitted wave and the reflected wave can be calculated by using the continuity condition at t… the gold bus glasgow
