The sensory manifestations of warmth have been associated with various physical and often common place experiences; the energetic sensation of heat through circulation from running, the application of a warm thermal pack to soothe muscle tightness, the stinging from a sunburn, or the comfort of a warm electric blanket to take a chill away are familiar. There are also fewer familiar applications of warmth from energy that are not as clearly understood in their dynamics including lasers, light emitting diodes, and electromagnetic radiation. Radiant energy is the energy of electromagnetics that takes the form of various invisible waves as kinetic energy. Like the laser and light emitting diodes, radiant energy is measured in joules and is based on the small light energy packets called photons that fuel the radiant energy from its source. Radiant energy is measured with its radiant influx, or power, with respect to time and is distributed according to the vibration of its photon particles. Most often, radiant energy is used to describe heat that may or may not be invisible to the naked eye and is typically harnessing thermal energy. This is the result of changes in the configuration of electrons and can travel through any substance – air, liquid, or space. However, radiant energy can be reflected if the object receiving the energy cannot absorb it. Energy has the circumstantial capacity to be reflected, refracted, or absorbed. Want to read more?
