Anyway, I am no expert on these matters; hopefully someone else can clarify this. | |

The particle loses energy via EM work done on the molecules of the medium (essentially creating dipole moments by distorting electron orbitars). This work is then soon converted to coherent Cherenkov radiation as those dipoles return to their equilibrium position. | |
