WhataBohr Posted April 15, 2009 Posted April 15, 2009 I know the answer to this but here goes light travels at c however when it reflects say off a mirror does it slow to zero and reversed direction???
YT2095 Posted April 15, 2009 Posted April 15, 2009 no, because it isn`t the same photon. they all start and end their "life" at c, there`s no Slowing or sub c.
swansont Posted April 15, 2009 Posted April 15, 2009 It gets absorbed and re-emitted. Which explains why there is Brewster's angle for polarized light. Dipoles can't emit in a particular direction (along their axis).
Kroughfire Posted April 15, 2009 Posted April 15, 2009 The photon boson force carrying particle might be the cause. The energy in the boson may just be to much after absorbing the photon that it immedietly releases it again, but I'm not exactly sure about how direction is determined.
WhataBohr Posted April 16, 2009 Author Posted April 16, 2009 I think one needs to look at when light hits a medium part is reflected and some is transmitted.. snell laws. I believe we need to look at propagation of light from a Electrodynamic way (maxwell equations) and Poynting theorem ( conservation of energy) Any thoughts
