PHY 114 Lab Report 9: Reflection and Refraction of Light . Arizona State University. ABSTRACT: The goal of this experiment was to verify Snell’s law and the law of reflection. By shining a laser ... through solid plastic and water, it became possible to study these these properties of light by measuring their angles of incidence, their critical angles and their angles of refractions. The slopes of i vs. θr and sin θ1 vs. sin θ2 for each medium made it possible to confirm Snell’s law, and the law of reflection due to low errors (1.29% and 0.8%) in the slope. In the same way, Snell’s law was verified due to low error (3.8% and 9.8%) in the slope as well. The critical angle made it possible to calculate the index of refraction, and when compared to the theoretical values of each medium, low errors of (2.329% and 6.316%) confirm that the experiment was completed successfully.
