It has a wavelength of 10-400nm. -It causes skin cancer and tanning when exposed for a long time.-It lies between the frequency of visible light and X-rays. WebbOzone is extremely valuable since it absorbs a range of ultraviolet energy. When an ozone molecule absorbs even low-energy ultraviolet radiation, it splits into an ordinary oxygen …
Webb5 apr. 2024 · Ozone is the major absorber of UVB (Ultraviolet radiant energy in the wavelength range 280-320 nanometres) in sunlight, absorbing approximately 90% of it. Many experimental studies of plants and animals, and clinical studies of humans, have shown the harmful effect of excessive exposure to UVB radiant energy. WebbThe ozone layer is found in the stratosphere, in the upper atmosphere, about 20 to 40 km above the Earth’s surface. This layer absorbs most of the sun’s UV rays, providing a natural sunscreen that protects life on earth. During the 1970s, scientists became aware that certain industrial chemicals were destroying ozone in the stratosphere.
WebbThis means that very low down, the ozone concentrations tend to be lower. From roughly 12 to 30 km, the two tendencies balance out, and the highest ozone concentrations are found there, in what is called the "ozone layer". This is why the ozone layer exists in the lower part of the stratosphere. The lower layer of the atmosphere that ...
