How does UVC light destroy viruses and bacteria?
Context UVC, a type of ultraviolet light within the wavelength range of 240-280 nm, has the unique ability to inactivate pathogens, including bacteria and viruses. But what exactly is the mechanism behind this inactivation process? Simple Answer UVC light damages the DNA and RNA of pathogens. This damage prevents pathogens from replicating and multiplying. Without the ability to reproduce, pathogens become harmless. UVC light doesn't kill pathogens outright but renders them inactive. The specific wavelength range of 240-280 nm is most effective due to its high energy levels and ability to penetrate the pathogen's protective layers. Detailed Answer UVC light's ability to inactivate pathogens stems from its high energy, falling within the ultraviolet spectrum. It's specifically the wavelength range between 240-280 nm that proves most destructive to pathogens like bacteria and viruses. When UVC light interacts with these microorganisms, it targets their genetic material -...
