It's the extension of the sphere's radius drawn to that point.
The normal vector to the surface is a radius at the point of interest.
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.
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
Sphere is one syllable: sphere.

no, its not normal
If you're a cat.
like normal cats eyes
yes it is perfectly normal because their eyes and body clouds over then their eyes go back to normal then will shed up to a week after the eyes go clear. :)
Emmetropia
eyes
no they do not
No, it is not normal. It is very uncommon but not unheard of.
In normal usage, all of them have a face.
