Question

$C{O}_2,C{H}_4,N_{2}O$, CFCs are called greenhouse gases because they can absorb

• A. Long wave infrared radiations
• B. Visible light radiation
• C. Ultraviolet radiations
• D. X-ray radiation

Answer 1

The correct option is A Long wave infrared radiations

Long-wave infrared radiations
The greenhouse effect is the phenomenon of heating the Earth’s surface due to the absorption of longwave infrared radiations by the greenhouse gases such as $C{O}_2,C{H}_4,N_{2}O$, CFCs etc. followed by their emission towards the Earth’s surface.
They do not allow the escape of the surface-reflected solar radiation back into space.
Since these gases contribute to the greenhouse effect, hence these are called greenhouse gases.

Final answer
(B) Long wave infrared radiations
