3O2 —UV —light——> 2O3
THIS IS AN EXAMPLE OF A REATION USING LIGHT.
IF ULTRAVIOLET LIGHT FALLS ON OXYGEN THE IT GIVES OZONE,THEN WHY MOST OF THE OXYGEN HAVE NOT BEEN CONVERTED TO OZONE.

This is because Ozone is dynamically created by UV and very quickly disintegrates into Oxygen molecules. It has a half-life of just minutes. There is some confusion about the half life. Ozone can exist for as short as micro seconds and sometimes for as long as 50 minutes. But on the whole, as an average, it has a half life of minutes.
By the time the heavier ozone sinks into the atmosphere, it has got converted back into Oxygen! Hence the reason Ozone is found only on the upper side of the atmosphere facing the sun.
Ozone is created by lightning during thunder storms also. That is what you smell. Unlike orderless Oxygen, Ozone does have a characteristic odour. You might get that smell in some public swimming pools.
So as the sun’s UV strikes our planet, Ozone is dynamically formed shielding the planet from the UV proportionally. So when there is more UV, more ozone forms creating more of a filtering shield, and when the UV is less, then very little Ozone is formed!!! If there is no UV, then there is no Ozone being formed!! So it is no surprise that in the poles, where the sun’s incident rays are at an greater angle, there is less intensity of UV to ‘create’ Ozone, hence there is less density of Ozone at the poles.
