The upper stratosphere consisting of the ozone layer protects us from the sun's radiation that falls in the wavelength region of :
600 - 750 nm
400 - 550 nm
0.8 - 1.5 nm
200 - 315 nm
Stratosphere -
Second layer of atmosphere , just above the troposphere
- wherein
Extends between 10 and 50 km above sea level.
Stratospheric pollutions -
Depletion of ozone layer due to certain compounds like nitrogen oxides , CFCs etc.
As we have learned in ozone layer .
Ozone protects most of the medium frequency ultraviolet light from 200-315 nm wavelength
600 - 750 nm
Option 2)400 - 550 nm
Option 3)0.8 - 1.5 nm
Option 4)200 - 315 nm
