Introduction
“紫外线”(紫外线)是电磁波谱的一部分不同结局的视觉光覆盖到x射线区域。这些射线对人体皮肤和视力有害。持续的消费“紫外线”会导致几个障碍。此外,“臭氧层”消耗了大量的“紫外线”,来自阳光。此外,“水星灯,黑灯,晒黑灯”几种紫外线的来源存在于大气中。
About the Electromagnetic Spectrum
“电磁(EM)图谱”是所有领域的分类辐射。“电磁辐射”来自不同来源,是构建“电磁波谱”背后的原因(网友,2022)。此外,辐射可以旅行和传播不同类型的“可见灯”。这些灯的来源主要是以下−
电台
发出的无线电波广播电台是一个源的电磁光谱,这些波进入大气,同时优化不同的广播电台的听众
红外
夜视眼镜和现代“闭路电视摄像头”用红外感应灯发射出的红外波。它可以帮助用户得到一个清晰的愿景。
微波
“微波辐射提取烹饪不同的东西在家庭或餐厅,烹饪不同的东西。“微波辐射”也是“电磁频谱”的来源是由天文学家信息附近星系的结构(库普里扬诺夫,Shafigulpn, 2018)。
紫外
“紫外线辐射”是另一种类型的电磁光谱太阳导致发布的“皮肤燃烧和疾病”。
x射线
“x射线辐射”是有用的电磁光谱扫描身体形象,出于安全原因,它是利用扫描不同的便携式项车站和机场。

Discovery of Ultraviolet Rays
“紫外线”是“电磁辐射”的家庭里的结尾部分光紫色,可见微小的“波长”。通常,紫外线灯都阳光发出更大的能源,不能被人眼可见的。“约翰·里特”在19世纪发明了紫外线,检查的欲望的存在,可见光谱的波,可以超越。第一次,它仍然是一个未知的照片以更快的速度变黑的蓝光(Ismlandmarks的影响。wordpress, 2022)。之后,这是表示,这部电影可以去紫,因此,紫外线灯的存在被建立

“Wavelength and Frequency of Ultraviolet Ray”
因为所有的电磁波可以在独特的旅行速度通过真空波长有不同频率的水平。每秒钟的时间重复,可以定义一波的频率。此外,赫兹是常见的SI单位测量频率的波。使用纳米为单位测量紫外波频率水平。此外,可见光源相比,紫外线波长更简洁,不能与肉眼可见(Sciencecompany, 2022)。此外,波长的紫外线出席能力从10 nm左右约400海里。它维护频率不同美元之间mathrm{800:太赫兹::30:PHz} $。
Figure 3“Ultraviolet radiation components”
根据类型的波长,紫外线辐射可分为三种不同的类型。所有不同类型的长度可以对人的皮肤有害紫外线灯(Sciencelearn, 2022)。此外,紫外线灯的长度更短对人的皮肤有害。分类是追随者−
UVA −“它包含美元的波长mathrm{315 - 400:海里}$”
UVB −“它包含美元的波长mathrm{280 - 315:海里}$”
UVC −“它包含美元的波长mathrm{100 - 280:海里}$”
Apppcation of Ultraviolet Rays
不同的现代世界的应用紫外灯都相应地提出了现在。这是参加在工业和商业意图。一般来说,用例的紫外线灯可以在管理水温度,净化空气,治疗皮肤,室内园艺,和其他人。以下是至关重要的操作−紫外线在当下时间
水处理
净化的水通过消除“微生物实体”使用波长200 nm - 310 nm范围之间的有效的能谱(王et al . 2018年)。发射出紫外线辐照过程中通过“电弧电”的形式推动蒸汽或气体可以消毒的水。
用例 生物
紫外线灯可以杀死人类细胞通过特定波长目标DNA损伤。有可能纳入这种治疗,这一过程的控制应用程序可能会伤害人类的身体器官(陈et al . 2020年)。辐射的应用可以帮助治疗不同的疾病杀死DNA停止人体疾病的蔓延。这个过程是完全取决于目标细胞的位置。
室内园艺
“多酚”的生产是一个有效的紫外线部分的应用程序。紫外线辐射的应用可以提高室内规划和大麻的财产增加不同的医学治疗。
Conclusion
在本教程中,有效性和电磁频谱的有害紫外线灯一直强调不同的用例。本教程还有助于占有用的应用从不同的角度紫外线灯。紫外线是一种类型的“电磁频谱”,它有一个有效的来源自然资源就是阳光。此外,形成了许多有益的应用程序,这些惊人的属性由紫外线带来的好处。与清晨和晚上,中午的时间是最直接从阳光紫外线的时间。
