The program simulates a ripple tank and displays the result in real time in three dimensions on the screen. In the tub objects may be placed (pathogen, column grid, observation points). The water surface can be colored depending on the amplitude / deflection so that nodal lines, antinodes and other interference phenomena are clearly visible. Also, one-dimensional waves (incl. Interference, reflection of solid and free end) can be simulated. The program consists of only one file that can be started immediately. Installation is not necessary.
