This document discusses the law of reflection, which states that the angle of incidence of a ray equals the angle of reflection. It notes that knowing this law allows one to predict where a ray will be reflected when encountering a surface by drawing the reflected ray such that the angle of incidence equals the angle of reflection. The document emphasizes practicing applying this law to accurately predict reflections on diagrams.
