Acoustic Lens (2D)

Interactive 2D geometric-acoustics simulator: a biconvex lens made of a slower- or faster-sound material bends an incoming plane wavefront via Snell's law and focuses it, with a live lensmaker-equation readout.

A flat 2D geometric-acoustics companion to the 3D acoustic lens: drag the curvature and material-speed sliders to reshape a biconvex sound lens, and watch the incoming plane wave refract at both faces via Snell's law into a converging (or diverging) wavefront, with the lensmaker-equation focal length tracked live against the actual ray-traced focus.
