What term refers to the angle formed by a reflected ray and the normal at the point of incidence?

The term that refers to the angle formed by a reflected ray and the normal at the point of incidence is indeed the angle of reflection. When a ray of light strikes a reflective surface, it interacts with the surface at a specific point known as the point of incidence. The normal is an imaginary line that is perpendicular to the surface at that point. The angle of reflection is measured between the reflected ray and this normal line. According to the law of reflection, this angle is equal to the angle of incidence, which is the angle formed between the incoming ray and the normal. Understanding this concept is crucial in optics, as it underpins how mirrors and other reflective surfaces work. The angle of reflection plays a key role in predicting how light behaves when it encounters different surfaces.
