UVstrålar
UVstrålar, or ultraviolet radiation, is a form of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. It is part of the electromagnetic spectrum emitted by the sun and is invisible to the human eye. UV radiation is typically divided into three categories based on wavelength: UVA, UVB, and UVC.
UVA rays have the longest wavelength and can penetrate the skin's deeper layers. They are primarily associated
Exposure to UVstrålar can have both beneficial and harmful effects. Beneficial effects include the production of
