SUMMARY

The discussion focuses on the electromagnetic interactions of light with matter, specifically addressing how light can be reflected or absorbed. Key concepts include the scattering matrix and quantization effects that lead to translucency or absorption. The conversation references Richard Feynman's book "QED: The Strange Theory of Light and Matter," which provides insights into internal reflections and phase changes. Participants express uncertainty about the nature of matter and its interaction with light, highlighting the complexity of these electromagnetic phenomena.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with quantum mechanics concepts
  • Knowledge of scattering matrices
  • Basic principles of light-matter interactions
NEXT STEPS
  • Read Richard Feynman's "QED: The Strange Theory of Light and Matter"
  • Study the principles of the scattering matrix in quantum mechanics
  • Explore the concept of internal reflections in optics
  • Research phase changes of light upon reflection and refraction
USEFUL FOR

Students and professionals in physics, particularly those interested in optics, quantum mechanics, and the fundamental interactions between light and matter.

If light encounters -normal- matter, the electromagnetic aspects of the influence of the electrons will be interacted with (I'm ignoring any stress contributuins to gravity) which is (scattering matrix?) either nothing at all (translucency) due to quantisation, or absorption.

Is this correct?

If so, how is it that light be reflected?

You might want to give Feynman's book "QED: the strange theory of light and matter" a try.
 
Yrs i have that book, unfortunately, it's in storage, and I've not seen an english-language version here. Sadly I am unable to memorise entire chapters I had read over ten years ago.
 
I do recall passages and diagrams concerning internal reflections and the phase-changes as result but the details are fuzzy now. Also, I seem to recall diagrams where light was an oscillating line and matter had a ' surface' marked by a continuous, thin line...

I am unconvinced that matter is composed of space thus bounded.
