This is a physically correct simulation of waves on a surface, for example water-waves. It can also be used to simulate Microwaves, and has features like the support for different refraction indices, different wave sources and custom borders. Therefore, experiments like the double-slit-experiment can be easily simulated. Features: - Physically correct wave simulation - Support of different refraction indices - Support of custom borders (e.g. double-slit) - Customisable visualisation colors
