UVA radiation cannot be seen with the human eye and might be least harmful to humans. The wavelength of the UVA is considered the longest with the lowest energy and is regarded as the least harmful. The most dangerous forms of rays in sunlight are the UVB and UVC. Being exposed to these rays of sunlight can lead to too complicated skin diseases and skin cancer, especially if you are not covered wholly during those periods. In the environment, ultraviolet radiation comes more from the sun than from any other source. Ultraviolet edition also comes from solar emissions and visible light. There are three divisions of the UV radiation spectrum, UVA, UVB, and UVC. The UVC radiation is absorbed by the ozone, water vapor, carbon dioxide, and oxygen as the sun passes through the atmosphere. UVA radiation is not filtered by the atmosphere.

Black Lights

Blacklight refers to a specific type of UVS system (ระบบ uvc ,which is the term in Thai) , usually in fluorescent lamps with special coatings that Emit UV radiation. The process through which materials meet the energy stored in them slowly indivisible Light Form can be known as phosphorescence. You can find this feature in those materials that usually glow in the dark. The materials absorb energy when they are exposed to light, and they emit energy in the darkness slowly.

Other Applications

Where are also other applications and sources of artificial UV lights? Some of these artificial sources include the fluorescent lamp, which has a UV coating and Emits UV light. The radiation that Emits from this lab can cause damage to the human skin when exposed to it for a lengthy period. It is also used as a form of disinfectant.

Many Industries utilize UV lights for specific processes. The LED and diodes used in UV light are used in digital printing to cure printed materials. LED lights and bulbs can be seen everywhere in our society.
