Key Concepts

Incandescence

Incandescence refers to the phenomenon where an object emits light as a result of being heated to a high temperature. When an object's thermal energy increases, it begins to radiate energy in the form of visible light, in addition to infrared radiation, as its atoms and molecules vibrate more vigorously.

Blackbody Radiation

Blackbody radiation is the theoretical concept that describes the spectrum of light emitted by an idealized object that absorbs all incident electromagnetic energy. This framework helps explain incandescence because it relates the temperature of an object to the characteristic spectrum of radiation it emits.

Thermal Radiation

Thermal radiation is the process by which all objects emit electromagnetic energy as a consequence of their temperature. This emission spans a range of wavelengths and becomes partially visible as incandescence when the temperature is high enough to emit light in the visible spectrum.
