Rainbow in a Droplet (schematic)
This interactive simulator explores Rainbow in a Droplet in Optics & Light. Snell + one internal reflection in a sphere; scan impact height and n. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Optics & Light.

How it works
Geometric optics in a spherical drop: not a full Mie simulation, but the correct sequence of refraction → reflection → refraction for one ray family.
