The discussion centers on finding the angle of refraction using Snell's Law, which relates the angles of incidence and refraction to the indices of refraction of the two media. Participants emphasize the importance of understanding the formula: n1 * sin(θ1) = n2 * sin(θ2), where n represents the refractive indices and θ the angles. A suggestion is made to consult HyperPhysics for further clarification and examples. The conversation highlights the relevance of Snell's Law in optics and its application in various scenarios. Understanding this principle is crucial for accurately calculating refraction in different mediums.
