Question

What type of radiations are absorbed by $CO_{2}$ in the atmosphere?

Answer 1

Carbon dioxide is considered as “one of the most” notable causative agent of greenhouse effect.  Once, it reaches the atmosphere, it is very difficult to reduce its level as it has strong affinity to the atmosphere layer of the earth.

In the earth's atmosphere, the carbon dioxide gas has the ability to absorb the radiation with wavelength of 15 μm (micrometers). Due to this affinity of the carbon dioxide as the infra red rays fall under the prescribed wavelength for carbon dioxide affinity, IR radiations are absorbed by it.
