ULTRAVIOLET RAY Meaning and
Definition
-
Ultraviolet ray, often abbreviated as UV ray, refers to electromagnetic radiation with wavelengths shorter than those of visible light but longer than those of X-rays. This form of radiation is not visible to the human eye, as it falls outside the visible spectrum at the higher energy end. Ultraviolet rays are categorized into three types based on their wavelength: UVA, UVB, and UVC.
UVA rays have the longest wavelength among the three types and penetrate the Earth's atmosphere to a greater extent. They are the least harmful of the UV rays but can still cause skin aging and some damage. UVB rays have a shorter wavelength and are partially absorbed by the Earth’s atmosphere. These rays are responsible for sunburns and can potentially cause skin cancer. UVC rays possess the shortest wavelength and are almost entirely absorbed by the atmosphere, thus rarely reaching the Earth's surface.
Ultraviolet rays are emitted by the sun but can also be produced artificially through means such as UV lamps for various applications. They have important uses in medicine, sterilization, and astronomy. However, excessive exposure to UV rays, especially UVB, can be harmful to living organisms, causing sunburn, eye damage, and an increased risk of skin cancer.
To protect ourselves from ultraviolet rays, it is recommended to wear sunscreen, sunglasses, and protective clothing when exposed to sunlight, particularly during peak hours. This reduces the risk of sunburn and potential long-term damage caused by excessive UV radiation.

Etymology of ULTRAVIOLET RAY
The word "ultraviolet" is derived from the Latin words "ultra" meaning beyond and "violet" referring to the color. The term "ray" simply indicates a beam of light. Therefore, "ultraviolet ray" refers to a form of light radiation that is beyond violet in the electromagnetic spectrum.
