That ray of light is just a radius of the sphere. It's perpendicular to the sphere everywhere, so the angle of incidence is zero ... the ray of light arrives along the normal to the mirror at any point.
It is called an arm of the angle.
Such a ray is called a "bisector" of the angle.
Angle Bisector

It does. But when the ray arrives perpendicular to the boundary, the angle of incidence and the angle of refraction are both zero, so its direction doesn't change.

The light ray arrives perpendicular to the plane of the mirror.
Answer: Angle bisector
Angle Bisector
Not exactly.A ray that divides an angle into two angles of equal measure is called an angle bisector.
The angle of incidence
