The broad emission spectrum from sources of this type is referred to as thermal radiation. Other sources of visible light, such as gas discharge tubes, are capable of emitting light in narrow, well-defined frequency ranges (representing a single color) that depend on specific energy-level transitions in the source material atoms.

Emissivity Coefficient Materials

The emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for some products varies with the temperature.
