Question

I don't know quantum mechanical model. So, I'm referring to just bohr's model of atom.

Any atom emits energy when it makes transition from higher excited state to lower excited state. Now, some times they say that this energy is light energy and some times heat energy.

I'm confused. What decides the emitted energy will be light or heat?

Do we have control over what kind of energy it emits? I mean can I make an atom emit light and not heat? or heat and not light? What are the factors influencing this?

Explanation / Answer

In the specific example of the light bulb, the current passing through the thin wire heats it to the point of incandescence. The molecules composing the wire, change energy states as they interact with the electrons of the current and emit a spectrum of electromagnetic radiation starting with infrared up to visible light in frequencies.

from the link:Unfortunately, the spectrum emitted by a blackbody radiator does not match the sensitivity characteristics of the human eye. Tungsten filaments radiate mostly infrared radiation at temperatures where they remain solid (below 3683 kelvins / 3410
