Prism Refraction Lab

Snell's law through a triangular prism with live deviation angle and total internal reflection detection.

n = 1.50 · A = 60° · θ₁ = 45°deviation δ = 37.4°critical angle = 41.8°

Deviation δ vs incidence θ₁

min δ ≈ 37.2°

The dot marks your current setting. Gaps in the curve are angles where the exit face undergoes total internal reflection.
