Where Is Uv Light On The Electromagnetic Spectrum

These are the classifications most often used in earth sciences.

Where is uv light on the electromagnetic spectrum. Ultraviolet light from our sun the sun is a source of the full spectrum of ultraviolet radiation which is commonly subdivided into uv a uv b and uv c. There are a number of subcategories of uv radiation including near middle far vacuum and extreme. The light that excites the human visual system is a very small portion of the electromagnetic spectrum. This electromagnetic radiation is not visible to the human eye because it has a shorter wavelength and higher frequency than the light our brain perceives as images.

The uv spectrum is just one part of the entire electromagnetic em spectrum. Uv radiation is present in sunlight and constitutes about 10 of the total electromagnetic radiation output from the sun. Infrared if it could be seen would be located just beyond the red side of the rainbow with ultraviolet appearing just beyond the violet end. It is located just above visible light if the different categories were ranked according to energy.

Em radiation with frequencies higher than those of visible light are often expressed in terms of energy. Uv c rays are the most harmful and are almost completely absorbed by our atmosphere. Uv ultraviolet light refers to the region of the electromagnetic spectrum between visible light and x rays with a wavelength falling between 400 and 10 nanometers.
