Ultraviolet Vs Infrared

Ultraviolet (UV) radiation is a type of electromagnetic radiation with wavelengths shorter than visible light, typically ranging from about 10 nanometers to 400 nanometers. It is divided into three categories: UVA, UVB, and UVC, each with distinct properties and effects. UV radiation is known for its ability to cause chemical reactions, such as those that lead to sunburn and skin aging in humans, as well as its role in synthesizing vitamin D. In addition to its biological implications, ultraviolet light is also utilized in various applications, including sterilization, fluorescent lighting, and in certain types of photography.

Infrared (IR) radiation is another form of electromagnetic radiation, with wavelengths longer than visible light, generally ranging from about 700 nanometers to 1 millimeter. It is primarily associated with thermal radiation, as objects at any temperature above absolute zero emit infrared radiation. Infrared technology is widely used in various applications, including night vision equipment, remote sensing, and thermal imaging. Additionally, infrared radiation plays a crucial role in heat transfer and is commonly harnessed in heating systems and communication technologies, such as fiber optics.
