This document discusses the law of reflection, which states that the angle of incidence equals the angle of reflection. It provides examples of predicting the angle of reflection for light rays hitting a surface at various angles of incidence, such as 65°, 30°, 25°, 35°, 90°, 37°, and 45° based on the law of reflection. The document emphasizes the importance of understanding and being able to apply the law of reflection to accurately draw diagrams showing the incident and reflected rays.
