We know light rays incident on a surface face three types of events.
- proportion of it is absorbed
- some of it is reflected &
- remaining part of it gets refracted.
In case of Total Internal Reflection, we know, not only does normal reflection occur (2), but also its refractive part (2) get reflected.
What happens to the (1) part? Is it also reflected or just get absorbed by the surface? If part (1) is absorbed like all other cases, why do we call it 'total'?
