Question

Carbon dioxide and water molecules in the atmosphere will absorb:

a. infrared light.b. visible light.c. ultraviolet light.d. radio waves.

Answer 1

For CO2 we know that it has a useful life in the atmosphere of the earth, sometimes long. Carbon dioxide has the ability to absorb energy with a wavelength of 15 µm, this makes carbon dioxide a good absorbent of wavelengths that are in this range, such as infrared radiation for example .

At the same time the water vapor has the capacity to absorb the radiation in a 50 µm and 2.9 µm spectrum, infrared radiation fluctuates over the same range.

Therefore the correct answer is A.
