SUMMARY

The discussion focuses on the phenomenon of light slowing down when it enters a medium such as glass or air. It emphasizes that the speed of light (c) is influenced by the electromagnetic field and the interactions with electrons in the medium. The conversation also touches on the dual nature of light, questioning whether it is best understood as particles or waves. Mathematical representations of this phenomenon are sought to illustrate the speed reduction in electron-containing media.

PREREQUISITES
  • Understanding of electromagnetic fields
  • Basic knowledge of wave-particle duality

I wish to understand why the speed of light slows down when it enters a medium such as glass or air.

Is this best understood by treating light as a stream of particles or a wave?

I have read that the speed of light (c) is a result of disturbance of the electromagnetic field. In contrast in media through which light is traveling the speed is a disturbance of the field which governs the position and speeds of the electron (in the material).

Is their any snippet of mathematics which can show how the light slows down in the electron containing medium.

Thank You
Adam
