ULTRAVIOLET SPECTRUM Meaning and
Definition
-
The ultraviolet spectrum refers to the range of electromagnetic radiation that has wavelengths shorter than those of visible light but longer than X-rays. It is situated between X-rays and visible light on the electromagnetic spectrum. The ultraviolet spectrum consists of various sub-bands categorized based on their wavelength: UVA, UVB, and UVC.
The UVA band, with longer wavelengths that typically range between 315 to 400 nanometers (nm), is also known as the "near ultraviolet." This type of ultraviolet radiation is the least energetic and is commonly associated with tanning beds and blacklights.
UVB radiation, with wavelengths between 280 to 315 nm, is often referred to as the "middle ultraviolet." It possesses more energy than UVA and can cause suntan, sunburn, and be harmful to the skin if excessively exposed.
The most energetic ulraviolet radiation is UVC, which has the shortest wavelengths, ranging from 100 to 280 nm. However, UVC is almost entirely absorbed by Earth's atmosphere, including the ozone layer, and does not significantly reach the planet's surface.
Understanding the ultraviolet spectrum is crucial in various fields, including physics, astronomy, biology, and sunscreen technology. Ultraviolet radiation has proven both beneficial and harmful, as it plays a vital role in processes like photosynthesis and vitamin D synthesis but can also cause skin damage, cataracts, and other health issues when overexposure occurs.

Etymology of ULTRAVIOLET SPECTRUM
The word "ultraviolet" is derived from the Latin words "ultra", meaning "beyond", and "violet", which is a color of light that has a shorter wavelength than visible light. The term "spectrum" refers to the range of wavelengths or frequencies of electromagnetic radiation. Therefore, the term "ultraviolet spectrum" describes the range of wavelengths of electromagnetic radiation beyond the violet end of the visible light spectrum.
