Infrared heating transmitted the energy

The energy that atoms and molecules can cause to move or shake by heating. the atoms and molecules doesn’t only contain degrees of freedom . it also include that heating of the vibrational degrees of freedom. vibration intensified of the atoms and molecules when it temperature increase with pressure the wavelength of vibrational happened to be in the Infrared range 。
In addition, the thermal effects of Infrared mean this frequences equals or is close to the frequences of Infrared, it can cause resonance, meanwhile Infrared which transmits energy by impact. Infrared radiant heating system according to the principle.
