Understanding UV Light

UV light, short for ultraviolet light, forms part of the electromagnetic spectrum, lying just beyond the visible light range detectable by the human eye. This spectrum is categorized into three primary types based on wavelength: UVA, UVB, and UVC.

  • UVA (315-400 nm): This is the longest wavelength and the least harmful type. UVA penetrates deep into the skin and can contribute to aging and long-term skin damage. It is commonly associated with tanning.
  • UVB (280-315 nm): UVB has shorter wavelengths and is more harmful than UVA. It is responsible for causing sunburns and plays a significant role in developing skin cancer. UVB rays vary in intensity and are stronger during the summer months.
  • UVC (100-280 nm): UVC boasts the shortest wavelengths and is the most dangerous type of UV radiation. Fortunately, natural UVC from the sun is largely absorbed by the Earth’s ozone layer and doesn’t reach the surface. However, it’s this type of UV light that is artificially replicated in various technologies due to its germicidal properties.
UVC light is a potent disinfectant used in a variety of applications. Its ability to destroy the molecular bonds that hold together the DNA of viruses and bacteria renders it an effective tool for sterilization and purification.
