WebAs another example, incandescent lamps rely on Joule heating: the filament is heated to such a high temperature that it glows "white hot" with thermal radiation (also called … Web7 jan. 2012 · The basic principle of incandescence is giving energy to atoms by heating. When a solid heats, it turns red first (at this point, the object emits enough radiation, so we can observe the colour). Red is the lowest energy colour in the visible range we can observe. Upon further heating, it becomes white.
