Mirror Reflexion: Does Photon Remain Unchanged?

[live4physics]

In case of mirror reflexion, a photon reflected is the same ?
There´s some atomic process in this fenomena ?

 

[Dmitry67]

As all particles are identical
the question 'is it the same' does not have any sense, because there is no experiment in principle which can determine if it is the same or not.

I mean, is the photon "reflected" at atomic level ?
There´s a magnetic fenomena in this ?

light can't penetrate a conductor. the conduction electrons will move so as to cancel out any electric field in the conductor. as a result the light is reflected from the surface. this is basic electrostatics

live4physics: the incoming photon is absorbed by an electron in the mirror, and then re-emitted almost immediately. Whether you consider this to be "the same" photon or not I suppose is up for personal interpretation.
