i
Light refracts at a boundary between media. Adjust the media, angle, and wavelength to explore Snell's law. Enable dispersion to see white light split into its spectrum. Ch. 30.2–30.3
Wavelength 550 nm
Incidence 40.0°
Show dispersion (white light → spectrum)
Light from upper medium (downward)
n₁ sinθ₁ = n₂ sinθ₂ θc = sin⁻¹(n₂/n₁) n(λ) = B + C/λ²
i
Drag the object distance through the focal point to watch the image transition from real/inverted to virtual/upright. Three principal rays are traced in real time. Ch. 30.4
