The discussion focuses on calculating the angle of incidence when a beam of light strikes a glass medium with a refractive index of 1.56. It establishes that the angle of reflection is twice the angle of refraction, which can be solved using Snell's Law. The relationship between these angles is critical for understanding light behavior at the interface of different media. This topic is categorized as introductory physics, making it accessible for learners.
