Green House Gases absorb radiation energy mostly in which of the following region of solar spectrum?

The correct answer is Infra-red.
Important Points

Greenhouse gases absorb and emit radiation within the thermal infrared range.

• This process is the fundamental cause of the greenhouse effect, which leads to global warming and climate change.
• The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
• These gases allow the shorter-wavelength radiation from the sun, including visible light, to pass through the atmosphere and warm the Earth's surface.
• The Earth's surface then emits this energy as longer-wavelength infrared radiation.
• The greenhouse gases absorb this infrared radiation, trapping heat in the atmosphere and keeping the Earth's surface warmer than it would be otherwise.

In contrast, X-ray and ultraviolet are not the main wavelengths at which these gases absorb radiation. Visible light is largely transmitted and absorbed by the Earth's surface, not by greenhouse gases.
