Everything you wanted to know about infrared heat

Ultraviolet range (electromagnetic waves 0.01-0.38 µm long) is proceeded directly by the visible light (0.38-0.78 µm) and in the end by the infrared (0.78-1000 µm). Unlike the first two ranges, the infrared has the longer waves. Infrared heat consists of the electromagnetic waves emitted by atoms. In the infrared spectrum when the rays reach the surfaces of objects, they transform the transmitted energy into heat.

What is infrared heat?

Most of the infrared heat is invisible. The shorter is the wave, the bigger is the energy emitted. According to the DIN5031 system, there are three spectrums: A (0.75-1.5 µm), B (1.5-4.0 µm) and C (4.0-1000 µm). This means that spectrum A has the strongest heat of energy, whereas spectrum C is the weakest one. The length of the heat wave indicates the way of heat and the form of energy. On the contrary, the intensity of heat indicates the overall quantity of energy over the time period. Generally, each object with temperature higher than the absolute zero (0°K = -273°C) emits the electromagnetic waves. The vibration of atoms in objects is proportional to the temperature of objects.
