Why does some energy radiate as light and some as heat in certain cases (like fire), and not the same type of radiation?

Question

So, if we take fire, how come not all of the energy is released as light, why is some of it released as heat as well as light?

Answer 1

Energy is all the same.
You may think of light, Heat, radiation and sound being four different things but it is the same thing… “energy” at different frequency’s.

When you burn a campfire the different fuels and parts of the fire radiate different wavelengths of energy, some you recognizes as heat ,some you recognize as light , some you recognize as a popping & cracking sound.
