SUMMARY
The discussion focuses on calculating the angle of refraction using Snell's Law, specifically for a ray of light transitioning between a gas (n = 1.00), a solid (n = 1.84), and a liquid (n = 1.61). The correct angle of incidence is determined to be 35 degrees, leading to a calculated angle of refraction of 18.2 degrees when transitioning from gas to solid, and 20.9 degrees when moving from solid to liquid. The participants clarify the correct application of Snell's Law, emphasizing the importance of using the angle of incidence accurately.
