Infraraudonojo

Infraraudonojo is a Finnish term that translates to "infrared" in English. It refers to a specific range of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. This part of the electromagnetic spectrum is invisible to the human eye and is primarily associated with heat. Objects with a temperature above absolute zero emit infrared radiation, with the intensity and peak wavelength of the emission depending on the object's temperature.

The applications of infrared radiation are widespread. In everyday life, we experience it as the heat we feel from the sun or a warm stove. Thermography, a technology that uses infrared cameras, allows us to visualize temperature differences and is used in a variety of fields, including building inspection, medical diagnostics, and night vision equipment. In industry, infrared heating is employed for drying, curing, and various manufacturing processes. Spectroscopy, which analyzes how substances absorb or emit light, utilizes infrared radiation to identify and study molecules. Furthermore, infrared communication is used in devices like remote controls. The term "infraraudonojo" therefore encompasses a fundamental aspect of physics with significant practical implications.
