Refraction & Dispersion

Experiment Instructions

Follow the detailed instructions on the worksheet to investigate Snell's Law and Total Internal Reflection
  1. Pick materials for the top and bottom media.
  2. Change θᵢ to see refraction, then try a high angle for TIR when n₁ > n₂.
  3. Move λ to see how dispersion changes n(λ) and therefore θt.
