  • Do the individual photons slow down? No. But those photons get absorbed by atoms along the way and then a new photon of light is emitted (nearly, but not literally, instantly) which then continues along it’s merry way at C until it encounters another atom. What slows down is the net speed of transport through a given medium.

Throwing them in a concrete desert with hot cars parked underneath would probably affect their performance significantly.
