Ultraviolet light is a general term for radiation with wavelengths from 0.01 to 0.40 microns in the electromagnetic spectrum. Sunlight has a lot of UV rays. Ultraviolet rays have a great impact on human life and biological growth. Ultraviolet light, also known as "ultraviolet light", has a wavelength range of 100-400 nanometers and is divided into UVA (315-400 nanometers), UVB (280-315 nanometers), UVC (200-280 nanometers) and vacuum ultraviolet (100-200 nanometers) ). Ultraviolet rays are located between violet light and Roentgen rays in the electromagnetic spectrum. Like other wavelengths of electromagnetic waves, they all obey the basic laws of electromagnetic motion. Ultraviolet rays cannot cause vision (i.e. outside the visible range). According to different wavelengths, only the UVA and UVB parts of ultraviolet rays can penetrate the protective layer of ozone and clouds to reach the earth's surface. The UV index refers to the degree of possible damage to human skin caused by the ultraviolet radiation in the sunlight reaching the ground when the sun is at its highest position in the sky during the day (usually around noon).
