Diffraction in the Quantum theory of light

[Mr K]

I need better Understanding of Diffraction.

Also I would to understand this diagram

[Klaynos]

So, what do you understand so far?

[Mr K]

Not much I understand that light and matter consist of particles that have the behaviour of a wavy line which but I cant really get my head around how diffraction works

This picture relates to diffraction in the classical theory of light based on Maxwell's equations.

 

The explanation in terms of photons and quantum theory requires quantum electrodynamics (QED).

 

For an explanation of QED at an accessible level by the true master of the subject either read Feynman's book QED or see the lecturs, by Feynman himself, that are the basis for the book at this site:
