Ultraviolet light is an electromagnetic radiation with wavelengths between 100nm to 400nm. It can be classified into three wavelength ranges: UV-C (100nm to 280nm; strong germ-killing ability), UV-B (280nm to 315nm; helps human body generate Vitamin B), and UV-A (315nm to 400nm; capable to solidify paint ink and oil).
There are a wide range of household products that are taking advantage of this technology. The most common example is UV lamps, which causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevents the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies. Due to this property, UV light is widely used in all kinds of industries such as house appliances, lightings, water purification and food contact products.
