Where Is Ultraviolet Light Located On The Electromagnetic Spectrum

To the left is an image of the sun taken at an extreme ultraviolet wavelength 171 angstroms to be exact.

Where is ultraviolet light located on the electromagnetic spectrum. 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. These ultraviolet light is emitted from sun. Uv c rays are the most harmful and are almost completely absorbed by our atmosphere. These are the classifications most often used in earth sciences.

An angstrom is a unit length equal to 10 10 meters this image was taken by a. The light that excites the human visual system is a very small portion of the electromagnetic spectrum. Ultraviolet light from our sun. A spectrum is a range of wavelengths rather than one specific wavelength the uv spectrum is just one part of the entire electromagnetic em spectrum.

The electromagnetic em spectrum is the range of all types of em radiation radiation is energy that travels and spreads out as it goes the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. Ultraviolet uv light has shorter wavelengths than visible light ranging from 100nm to 400nm nanometers. The other types of em radiation that make up the. Only the lower frequencies of near ultraviolet waves are visible.

Uv b rays are the harmful rays that cause. Em radiation with frequencies higher than those of visible light are often expressed in terms of energy. The high energy ultraviolet radiations from the sun is mostly blocked by the ozone layer in the atmosphere so that these harmful radiations can t reach to the earth surface. Ultraviolet uv light is electromagnetic radiation with a wavelength shorter than that of visible light but longer than x rays that is in the range 10 nm to 400 nm corresponding to photon energies from 3 ev to 124 ev 1 ev 1 6e 19 j.

A rainbow shows the optical visible part of the electromagnetic spectrum. To understand ultraviolet radiation uv one needs to know uv s placement in the electromagnetic spectrum. There are a number of subcategories of uv radiation including. The sun is a source of the full spectrum of ultraviolet radiation which is commonly subdivided into uv a uv b and uv c.

It is located just above visible light if the different categories were ranked according to energy. When people refer to ultraviolet uv light they usually mean the uv spectrum. Ultraviolet uv is a form of electromagnetic radiation with wavelength from 10 nm with a corresponding frequency of approximately 30 phz to 400 nm 750 thz shorter than that of visible light but longer than x rays uv radiation is present in sunlight and constitutes about 10 of the total electromagnetic radiation output from the sun it is also produced by electric arcs and specialized. Our sun emits light at all the different wavelengths in electromagnetic spectrum but it is ultraviolet waves that are responsible for causing our sunburns.
