A false color photograph with ultraviolet radiation (335-365nm) mapped to the blue channel, green light (500-600nm) to the green channel and infrared radiation (720-850nm) to the red channel. Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ...
The "chemical rays" found by him were afterwards called ultraviolet radiation. [ 7 ] [ 8 ] [ 9 ] Some of Ritter's researches were acknowledged as important scientific contributions, but he also claimed the discovery of many phenomena that were not confirmed by other researchers.
William Herbert Rollins (June 19, 1852 - 1929) was an American scientist, inventor, and dentist. He was a pioneer in radiation protection.Many of his inventions and investigations in medical radiography and photography have been ranked in importance with those of Thomas A. Edison, Elihu Thomson, and William J. Morton.
New research from the University of California, San Diego could solve a mystery that scientists have puzzled over for several years.
Ozone is transparent to most UV-A, so most of this longer-wavelength UV radiation reaches the surface, and it constitutes most of the UV reaching the Earth. This type of UV radiation is significantly less harmful to DNA, although it may still potentially cause physical damage, premature aging of the skin, indirect genetic damage, and skin cancer.

Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma-ray astronomy. [1] Ultraviolet light is not visible to the human eye. [2]
Doritos are a revered snack for many. Now, scientists have found one of the ingredients in the triangle-shaped tasty tortilla chips has a superpower – it can make the skin of mice transparent.
