UV Light - Research Paper Example

Disadvantage of excessive sunlight consumption is that it can cause sunburn and other skin related diseases. Ultraviolet light has many uses for instance, in astronomy, to cause resistance against infections and in light bulbs using fluorescence. The word ultraviolet stands for beyond violet. In the spectrum of light which is visible, the wavelength of light tends to decrease whereas the energy that is present in the electromagnetic waves keeps on increasing. The range starts from red and changing from orange, yellow, green, blue and all the way to violet.

Therefore, UV light is shorter in wavelength and possesses more energy than violet radiation waves. Usually UV light is measure in nanometers. The range defined for ultraviolet range is between 10nm to 400nm. The characterization of ultraviolet light can from UV-A, UV-B or UV-C that depends on how the wavelength is decreasing. Another way to classify ultraviolet when it comes to astronomy is by characterizing through near, middle, far and extreme. Ultraviolent light has many benefits for example the UV light present in the sunlight can produce vitamin D which is essential for human growth and prevents from many harmful diseases like cancer, heart diseases, rickets etc.. The UV light present in the sun activates a chemical in our body that eventually formulates the vitamin.

It is observed that an excessive absorption of sunlight can cause skin diseases and sunburn. "Ultraviolet light has been used for centuries to treat a myriad of health and skin problems in the form of natural sunlight or more recently by artificial UV generated sources." (Baranoski, 154) Another purpose of ultraviolet waves is that it is used in the restoration of artwork.Ultraviolet waves help in restoration of art therefore while buying, framing, selling or praising an artwork knowledge of its prior restoration is necessary therefore while restoring
