Emissive power meaning
WebAll physical substances in solid, liquid, or gaseous states can emit energy via a process of electromagnetic radiation because of vibrational and rotational movement of their molecules and atoms [2]. The intensity of such energy flux depends upon the temperature of the body and the nature of its surface [3]. WebThe emissive power is defined as the ratio of energy radiated and emitted per unit area per sec to the amount of heat energy emitted per unit area per second by a perfectly black body at the same temperature. When a body’s temperature …
