Does the exact same photon of light bounce back or is it absorbed and a new one with the same properties emitted? how does it remember its path? And if it bounces back, does its velocity comes to near zero for a small-time before being reflected back in a straight line at same angle.

This question makes little sense.
Suppose you have a wave on a lake bouncing off the shore. Is the wave that bounced the same wave or a different wave with the exact same properties?
IIRC there is evidence that all photons are the same single photon, just in different places, but I really don’t have enough knowledge about this topic to talk about that.
