Understanding what ultraviolet means in science requires examining its position in the electromagnetic spectrum and its interactions with matter. UV-A, UV-B, and UV-C Scientists further divide the ultraviolet spectrum into three main categories based on wavelength and energy level.
Difference Between UVA, UVB, and UVC Explained
However, the Earth's ozone layer acts as a protective shield, absorbing the most dangerous UV-C rays and a significant portion of UV-B. UV-B rays fall in the middle, spanning wavelengths from 280 to 315 nanometers, and are more energetic than UV-A.
UV-B: Medium-wave ultraviolet, responsible for sunburn and vitamin D synthesis. This absorption prevents this high-energy radiation from reaching the surface in concentrations that would be lethal to most life forms.
