Correct Answer: Angle of Reflection
Solution : The correct option is the Angle of Reflection.
The angle measured from the reflected ray to the normal surface is called the "angle of reflection." The angle of reflection is the angle between the reflected ray and the normal (a line perpendicular to the surface at the point of incidence). It follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
The normal is an imaginary line perpendicular to the surface at the point where the light ray strikes.
