Ezekiel Tulloch, Period 3
Ultraviolet light is a type of electromagnetic radiation, as are radio waves, infrared radiation, X-rays and gamma-rays. UV light, which comes from the sun, is invisible to the human eye. It makes black-light posters glow, and is responsible for summer tans — and sunburns. However, too much exposure to UV radiation is damaging to living tissue. Ultraviolet wavelength range 100-400 nm and is divided into three bands and travels 186,000 miles per second in a vacuum. Ultra violet rays are used for destroying bacteria, and highlighting germs on surfaces.
