WebA harmonic sound wave enters the computational domain from the right end. The wave then travels through the tube. The left end is then treated as a sound hard boundary. When the wave comes back to the right end it is absorbed. This process of being a pressure source and absorbing the reflected wave is the radiation boundary condition. WebThe wave before hitting the boundary is known as the incident wave. The wave after encountering the boundary is known as the reflected wave. How the wave is reflected at the boundary of the medium depends on the boundary conditions; waves will react differently if the boundary of the medium is fixed in place or free to move (). braava jet m6 spot clean

Why do waves reflect in phase off of soft boundaries?
