In which wavelength range, the greenhouse gases absorb energy?

Correct option is D

✅ (d) 5 to 100 µm
· Greenhouse gases absorb longwave infrared radiation primarily in the 5 to 100 µm range.
· This is part of Earth's outgoing thermal radiation spectrum.
· Gases like CO₂, CH₄, N₂O, and H₂O vapor absorb in this range, trapping heat in the atmosphere (greenhouse effect).
❌ (a) 100 to 500 µm
· This range corresponds to far-infrared and microwave radiation, beyond typical greenhouse gas absorption bands.
❌ (b) 400 to 700 nm
· This is the visible light spectrum, primarily involved in photosynthesis, not in greenhouse gas absorption.
❌ (c) 0.3 to 3 µm
· This range includes ultraviolet to near-infrared, mainly part of incoming solar radiation, not Earth's outgoing longwave radiation.
