Scientists think that if we heat a certain body to an infinite temperature, the wavelength is zero !! that is there is no light at all, in other words there is black radiation and the resulting fire resulting from burning this body of the infinite temperature is dark black.
That is why a charcoal fire burns with no smoke. The actual burning of wood then happens in two separate reactions: When the volatile gases are hot enough (about 500 degrees F (260 degrees C) for wood), the compound molecules break apart, and the atoms recombine with the oxygen to form water, carbon dioxide and other products.
