The _______ of a ray is the angle measured from the reflected ray to the normal surface.

Angle of Reflection

The correct answer is option 2. Angle of Reflection.

The term that describes the angle measured from the reflected ray to the normal surface is angle of reflection.

The angle of reflection is defined as the angle between the reflected ray and the normal to the surface at the point of incidence. It is an important concept in the study of reflection of light and other waves from surfaces. According to the law of reflection, the angle of reflection is equal to the angle of incidence, which is the angle between the incident ray and the normal to the surface at the point of incidence.
