When it exits the glass how does it regain that energy which it must do to accelerate to the speed of light in air? |
Sorry but you mix up speed with energy. The light regains its speed but not its initial energy.It is common sense that light passing through glass comes out with less intensity/energy. Less "amount" of light comes out analogous to less "mass" |

Errr.... are you saying the mass of the photons decreases???????
You're all getting confused.... light has properties of both particles and waves. Think of it as a waveform to understand refraction. C'mon, my A-level physics enables me to understand it alright without me needing to be a professor of quantum or particle physics! |

Easy, tiger! 
I guess if all your posts suddenly start getting deleted, we'll know how she feels about your comments  |
