The ratio of the emissive power of the surface to the emissive power of a perfectly black body is called emissivity. White light originates from a variety of natural and artificial incandescent sources, including the sun, chemical reactions (such as fire), and incandescent.

The heat emitted by a flame that is provoked by a fire. Other forms of kinetic energy include thermal energy, sound energy, motion energy, and electrical energy. Kinetic energy refers to the movement of energy, whether it is in the form of atoms, molecules, waves, substances or objects.

From Stephen’s law, the rate at which an object radiates energy is proportional to the fourth power of the absolute temperature of the object and it is given by Electromagnetic waves: These are the most common type of radiant energy, and include radio waves, microwaves, infrared radiation, visible light, ultraviolet. Here are some examples of different forms of radiant energy: The energy emitted by the Sun and stars. Radiant energy is a form of kinetic energy.
