The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation. Thermal radiation is electromagnetic radiation that most commonly includes both visible radiation (light) and infrared radiation, which is not visible to human eyes. A portion of the thermal radiation from very hot objects (see photograph) is easily visible to the eye. The emissivity of a surface depends on its chemical composition and geometrical structure.

WebSurface Emissivity vs Reflectivity. Opaque (non-transparent) surfaces produce a combination of emitted and reflected radiation. Because the reflected radiation isn’t related to the surface temperature, we must tell the imager to disregard that portion of what it sees. To do that we correct for emissivity (E). Reflection (R) equals 1 minus E. WebOverview. Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero. Thermal radiation reflects the conversion of thermal energy into electromagnetic energy.Thermal energy is the kinetic energy of random movements of atoms and molecules in matter.
