UVChullámhosszak

UVChullámhosszak refers to the wavelengths of ultraviolet (UV) radiation. UV radiation is a form of electromagnetic radiation with wavelengths shorter than visible light and longer than X-rays. It is typically divided into three bands based on wavelength: UV-A, UV-B, and UV-C. UV-A has the longest wavelength, ranging from 315 to 400 nanometers (nm). UV-B spans from 280 to 315 nm, and UV-C is the shortest, from 100 to 280 nm.

The Sun is a major source of UV radiation, but the Earth's atmosphere, particularly the ozone layer, absorbs most of the harmful UV-B and virtually all UV-C. UV-A can penetrate the atmosphere and reach the Earth's surface. Different UV wavelengths have varying biological effects. UV-B is primarily responsible for sunburn and contributes to vitamin D production in the skin, but it also plays a significant role in skin cancer development. UV-A penetrates deeper into the skin and can cause premature aging and contribute to skin cancer. UV-C radiation is highly germicidal and is used in sterilization applications, but it is almost entirely blocked by the ozone layer. Artificial sources of UV radiation include tanning beds, germicidal lamps, and black lights. Understanding UV wavelengths is crucial for applications in medicine, industry, and environmental science.
