I'm not sure what you are asking, but the answer to your question is possibly Maxwell's Equations.
Maxwell's Equations are a set of partial differential equations that describe the cyclic exchange of energy between a changing electrical field and a changing magnetic field. Unfortunately I cannot enter the equations themselves on this site as they require characters in fonts that are not supported by the current Answers.com software.
E = hc/l
Convection and radiation (internally) and radiation (externally).
The packet of electromagnetic radiation is the photon.
Electromagnetic radiation is transferred by electromagnetic waves. Electromagnetic radiation is a fundamental phenomenon of electromagnetism.

Telescopes focus electromagnetic radiation for closer observation.
They are not different.Visible light IS electromagnetic radiation.
Radiation
electromagnetic radiation includes all types of the electromagnetic spectrum
Electromagnetic Radiation requires no medium. Light is a form of electromagnetic radiation, and it can traverse the stars.
the fundemental source of electromagnetic radiation is an ionic explosion
