    Well I have a basic (very basic) understanding of how/what radiation is. How is energy (more specifically kinetic/heat) turned into radiation?

    This relates to a bigger question I have, but I'm trying to figure out the test of it on my own...






    Also does anyone maybe have a link to what a practical number (in atmospheres?) to expect to be able to create in a vacuum is(lab quality)?


    WHAT?!

    To "Radiate" means to "give off".

    The fillament inside a light bulb "radiates" heat and light, as does the sun. Some chemical elements are "radioactive" Put simply this means they are "Actively Radiating". I.E They are "giving off" certain particles.


    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    Yes I know what radiation is and the many forms and how it works at a basic level.

    I'm asking for a more in depth explanation, in example: could heat be converted directly into microwave or light radiation?
    WHAT?!

    Heat is electromagnetic radiation somewhere between the two.

    As fas as I know you can only convert to a lower frequency by using matter to interact such as UV light shining on certain materials and giving off 'white' light in a disco. At much lower freguencies [in the radio band] it is easy using electronics but as to direct conversion I don't think so.

    Another possibility is is that the source is moving toward or away from you causing a dopplar shift such as the Cosmic background radiation.

    Hmm okay, thanks Mega. I was hoping to turn heat into a form of radiation that could be transfered through a vacuum therefore removing it from the insulated source without any contact to another object (suspended in the vacuum as in space), but I suppose this is not possible.
    WHAT?!
