Ripples

Interactive 2D/3D ripples simulator with amazing physical effects like diffraction, refraction, Doppler, etc. Draw walls and…Select the number of wave sources, frequencies and phases to generate ripples. Draw walls and waves of scene and observe the results.

Options:
- Mouse Modes: Edit the waves. Edit the walls.
- Display options: color schemes, 3-D view, wall eraser, waves eraser.
- Simulation options: Speed, Size, Resolution, Frequency, Play/Pause.
- Predefined scenarios that can be loaded and then change:

Single, Two & Four Source, Single, Double & Triple Slit, Obstacle, Half Plane, Dipole Source, Lateral & Linear Quadrupole, Hexapole, Octupole, 12-Pole, Plane Wave, Phased Array, Doppler Effect, Sonic Boom, Matrix Modes, Acoustic Modes, Coupled Cavities, Beats, Slow Medium, Refraction, Internal Reflection, Anti-Reflective Coating, Even & Odd Zone Plate, Circle, Ellipse, Resonant Cavities, Room Resonance, waveguides, Parabolic Mirror, Sound Duct, Baffled Piston, Low-Pass, High-Pass & Band-Stop Filter, Planar Convex, Concave & Biconvex Lens, Circular, Right-Angle Prism & Joint, Scattering, Lloyd's Mirror, Temperature Gradient Dispersion
