Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

The permittivity and permeability are constants that have to be experimentally measured.

Agha, your question has already attracted one Move to MathSE vote, so I've tried to rewrite it in a way more applicable to the PhysicsSE. However this is a big change. If you don't like my change please roll it back.

Ray, this can be readily Googled. For example Wikipedia gives a brief derivation. You'll need to expand your answer e.g. to pinpoint any issues of the derivation you're unclear about.
