Ripple effect mapping

Ripple effect mapping

Ripple tank simulation that demonstrates wave motion, ripple effect mapping, diffraction, refraction, Doppler effect, etc. Demonstration of wave motion in 2-D. Demonstration of wave motion in 3-D.

Demonstration of longitudinal wave motion in oscillators connected by springs. Simulation of wave motion of a string. Vibrational modes in a 2-d membrane. Acoustic standing waves in a 3-d box. Generates audio interference between your speakers. Filters digital signals and plays the output on your speakers. Demonstrates static electric fields and steady-state current distributions.

Demonstrates electric fields in various 3-D situations. Demonstrates magnetic fields in various situations. Demonstrates electromagnetic radiation, induction, and magnetostatics. Electromagnetic waves in a 3-d rectangular cavity. Single-particle quantum mechanics states in one dimension. Circular square well in two dimensions. Particle confined to the surface of a sphere.

Demonstrates the dot product or scalar product of two vectors. Demonstrates 2-d transformations using a matrix. Demonstrates various properties of vector fields, including divergence and curl, etc. Demonstrates vector fields in 3 dimensions.

Includes the Lorenz Attractor and Rossler Attractor. Demonstrates the kinetic theory of gases. This is not an applet but I thought I’d throw it in here anyway. Provides a visual comparison of various distances, from very small objects like protons and electrons, to distances between galaxies. Not an applet, but I thought I’d include it here anyway. Demonstrates Taylor series expansion of complex exponentials. Also here are more applets from Northwestern University.
