A specular angle is the reflected angle of a light ray that is measured from the normal to the surface of a mirror.

Question

Quizplus · Accepted Answer

The specular angle, also known as the angle of reflection, is indeed the angle at which a light ray, after hitting a reflective surface, bounces off measured from the normal (an imaginary line perpendicular to the surface at the point of incidence). According to the law of reflection, the angle of incidence (the angle at which the incoming ray hits the surface, measured from the normal) is equal to the angle of reflection (the specular angle).
