Final answer:
The angle between the normal and the reflected ray is called the angle of reflection, which is equal to the angle of incidence, according to the law of reflection.
Step-by-step explanation:
According to the law of reflection, the angle between the normal to the surface and the reflected ray is known as the angle of reflection. This is equal to the angle of incidence, which is the angle between the normal and the incident ray. Both angles are measured from the normal, which is the line perpendicular to the reflective surface at the point where the ray hits the surface. When a ray of light reflects off a surface, these two angles are the same.
