What is QED?

Answer QED is an abbreviation for the Latin "quod erat demonstrandum" (literally, "which was to be demonstrated" or "thus it is demonstrated". It is used at the end of a proof or logical argument by the author to state that… Full Answer

What is elecrtodynamics?

The correct spelling is electrodynamics. Electrodynamics is a branch of mechanics. It is the study that is concerned with the moving electric charges and the interactions with magnetic fields. Full Answer

How does light reflect off of objects?

A photon is absorbed by an electron and then it is emmited to a different direction. Quantum electrodynamics can give you a better answer to your question. There is a book i have read recently called QED: The strange theory… Full Answer

What is the particle model of light?

The particle model of light entails that light consists of tiny packages of energy called photons. Because light is an electromagnetic wave the model is a part of the general model for electromagnetism. This model is called Quantum Electrodynamics, or… Full Answer
