Why the Sky Is Blue (Rayleigh)
This interactive simulator explores Rayleigh Sky (blue) in Optics & Light. Scattered intensity ∝ λ⁻⁴; compare blue vs red and qualitative sky gradient. 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: Suited to beginners and first exposure to the topic. Typical context: Optics & Light.

How it works
The λ⁻⁴ factor is the small-particle limit; Mie theory matters for larger aerosols. This page isolates the wavelength dependence that students meet first.
