Another photon approaching at the speed of light.
Photons have no sensory organs so they cannot "see" anything.
Elie sees a reflection of himself when he looks in the mirror.
A photo. A mirror produces a 'mirror-image'
Elie sees himself staring back at him, never leaving his memory.
i was wondering to! but in the shadow at the water's edge Nancy looks in the mirror and you see what she looks like!
Substitute "photon" for "ray" and it's one. One photon falling on a plane mirror will come back off of the reflective surface if that reflective surface does not absorb it. (In a perfect plane mirror, every photon that falls on the surface will be reflected.) A photon does not "create" a second photon in a reflection event.
Elie saw himself as a corpse gazing back at him when he looks in the mirror at the end of the book and it is significant because he thought he did not deserve to survive.
Elie sees himself in the mirror at the end of the book as dead corpse gazing back at him.
When someone looks in the mirror they do not see themselves as others do. Every person has a different perception of how people look. When you look in the mirror, you see your left eye on the left but when other people look at you, they see your left eye on their right so yes, the image is somewhat flipped.

Assuming the photon is reflected into the same medium it came from (so we can ignore refraction), its momentum differs only directionally, its magnitude stays the same. The directional component of its momentum vector is always pointing in the direction it's propagating. Refraction is the means by which the magnitude component of the vector changes. The change in momentum of photon is nh/lambda.
a mirror is translucent even though it looks transparent.
The photon doesn't have a figure one can relate to. We can't say a photon looks like this -- or like that, because there's nothing in the world we see with our eyes day by day that looks like a photon.
