Question

UV light, especially UVC wavelengths, has enough energy to damage the DNA of bacteria, viruses, and other microorganisms. When UV light hits these germs, it breaks down their genetic material so they can't reproduce or survive. This is why hospitals use UV lamps to sterilize medical equipment and operating rooms, and water treatment facilities use UV light to purify drinking water without adding chemicals. It's a clean and effective way to kill harmful pathogens.​ make it simpiler

Answer 1

UV light — especially the strongest kind called UVC — destroys the tiny “instruction code” inside bacteria and viruses so they can’t live or reproduce. That’s why hospitals use UV lamps to disinfect rooms and equipment, and water plants use UV to clean drinking water without adding chemicals.
