Heat as Electromagnetic and Molecular Kinetics

  1. Feb 1, 2016 #1
    Consider the image below
    Does it emit all 3 types of heat in the form of UV, IR and light?
    At what threshold does light start to appear and what colors should it illuminate?
    Hypothetically, say I have an induction furnace and is capable of setting frequencies to about 700THz, will it be able to illuminate a colored(violet) light at that frequency?
    So, what limits its color? Does the illumination depends on molecular or electron dynamic response? I'd be delighted to see response from the forum. Thank you.

    T > 0K is "all" types of heat; at first I read this as "all transport mechanisms" but your phrasing is a bit ambiguous.
