What is an ir?

An IR, or Infrared Radiation, is a type of electromagnetic radiation that is invisible to the human eye but can be felt as heat. It has wavelengths longer than visible light, ranging from about 700 nanometers to 1 millimeter.

IR radiation is commonly used in various applications, including communication (such as TV remote controls), thermal imaging (used in night vision equipment and medical imaging), and heating (such as in infrared saunas).

IR radiation is also used in spectroscopy to analyze the chemical composition of substances by measuring the absorption or emission of infrared light. This technique is widely used in scientific research and industrial applications.

One potential concern with IR radiation is that it can cause skin burns or eye damage if exposure is prolonged or at high intensities. Therefore, it is important to use protective measures when working with IR sources.
