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.
Carbon black is a lot like graphite. Carbon black can form as an air-polluting particle when fuels (like gasoline, diesel fuel and coal) are not completely burned. These carbon black particles are often coated with other chemicals making them more hazardous than commercially produced pure carbon black.
