How has UV Light's wavelength helped humans or other living creatures?
Weegy: Using UV light to sterilize animal viruses has been proposed as a safe and effective way to clean work surfaces in veterinary settings and prevent the spread of virus-borne illnesses. [ Studies done using UV light to disinfect/kill animal viruses have shown the light can effectively kill or deactivate viruses, bacteria and microorganisms that are harmful to both animals and humans, according to the Science Learning Hub. The UV light penetrates the virus' membrane, eliminating the DNA, which the virus uses to reproduce itself. The virus then has no way of multiplying and eventually dies off. This makes UV light very effective in eliminating viruses at the source of their reproduction and is done so without synthetic chemicals.
