ultraviolet radiation ozone layer

"The ozone layer" refers to the ozone within stratosphere, where over 90% of the earth's ozone resides. Ozone is an irritating, corrosive, colourless gas with a smell something like burning electrical wiring. In fact, ozone is easily produced by any high voltage electrical arc such..

Ozone layer or ozonosphere refers to the ozone within stratosphere Where over 90 % of the earth's ozone is available. Ozone in the ozone layer is formed spontaneously by the action of solar ultraviolet radiation (wavelength of 180240 nm) on oxygen. ..

It refers to 'decrease in the amount of ozone in the stratosphere'* which is of vital significance to all living forms. It protects us from the ultraviolet radiation of the sun which is harmful to most living things. When there is less ozone in the stratosphere, more ultraviolet rad..

There is always a fixed concentration of ozone in the stratosphere and the importance of this layer has already discussed. Any decrease in concentration of ozone from its normal value means that there is a depletion of ozone layer. The ozone layer may be depleted by..

. An equilibrium is produced between generation and destruction of O3 resulting in steady state concentration in the stratosphere at a height of 20-26 km above the sea level. The concentration of ozone in this part is 0-310 ppm. Ozone is mostly formed over the equator. Global air circulation pushes..

Ozone layer present around the earth in the stratosphere protects the earth from the harmful UV radiation falling on it. But, due to industrialization, certain chemical substances enter the atmosphere which react with ozone and destroy 'it. Some familiar compounds among those are 1) Chloro ..

Ozone (O3) a light bluish gas found in the stratosphere absorbs ultraviolet (uv) radiations of the sun which is harmful to the living things. The concentration of ozone at a height of 25 to 30 km of the earth is 10 ppm. Ozone absorbs the ultraviolet radiatio..

;">f) They are used in hardening casts in medicine. 4. Visible Light a) The most interesting part of electromagnetic radiation is the visible light. The frequency ranges between 7.5 10 14 - 4.310 14 Hz b) V-violet, I-Indigo, B-blue, G-green, Y-yellow, O-orange, R-red are the colors of the Visible light spectrum. c) Th..

(CFCs). Another cause of depletion of ozone layer is emissions from jet aeroplanes. Chlorofluorocarbons have the largest ozone depletion potential (ODP). Chlorofluorocarbons when released from air conditioners, refrigerators, spray cans and industrial solvents drift in the stratosphere veiy slowly. Therefore, each chl..

The region of stratosphere, at an altitude of 23-26 km over equator and at a slightly lower altitude elsewhere, having a thick sheet of ozone is called ozonosphere. As per estimates, 90% of the total atmospheric ozone is present in this region. Ozone is a form of oxygen. The molecule of ozone..
