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.
A fire can be stopped in three different ways, by removing any of the three things it needs to burn: 1  The fuel can be removed. If a fire burns through all of its fuel and extra nearby fuel is removed, the fire will stop burning.  The oxygen can be removed.
