Interactive Simulations
Ten HTML5 canvas experiments — adjust the parameters, interact with the physics, watch it unfold.
Waves
Two wheels on an axle cross from fast to slow surface. The leading wheel slows first and the system bends — a mechanical model of Snell's law.
Open →Waves
Transverse and longitudinal waves with a tracked particle. Tune frequency, wavelength, and amplitude live.
Open →Optics
Drag a flashlight and measure angles of incidence and reflection against a protractor.
Open →Optics
Drag a laser pen around a circular water tank. Snell's law bends the beam; push the angle far enough and total internal reflection snaps it back.
Open →Optics
Mix red, green, and blue lights to see how additive color works. All three together make white.
Open →E&M
Wire a battery, switch, and lamp in a drag-and-drop circuit builder.
Open →E&M
Drag bar magnets into a field meter. Watch disordered domains align into a stronger permanent magnet.
Open →E&M
Slide a known magnet and watch compass needles pivot to identify the unknown poles.
