Do all molecules absorb electromagnetic radiation at some frequency?
No, not all molecules absorb electromagnetic radiation at a distinct frequency. The ability of a molecule to absorb radiation depends on its structure and the energy levels of its electrons. Molecules with specific functional groups or electronic configurations exhibit absorption at characteristic frequencies.
The earth's atmospheric green house effect is produced mainly by water vapour and carbon dioxide absorbing and re-emitting what?
Infrared radiation. Water vapor and carbon dioxide molecules in the Earth's atmosphere absorb infrared radiation emitted by the Earth's surface, preventing it from escaping into space. They then re-emit this energy in all directions, helping to keep the Earth's surface warmer than it would be otherwise.
Does all molecules have infrared spectrum?
All molecules have an infrared spectrum.
Which layer of the atmosphere does not absorb solar radiation?
Troposphere does not absorb solar radiation. All other layers do not absorb.
Is electromagnetic radiation infrared radiation?
Yes, electromagnetic radiation includes infrared radiation, which has longer wavelengths than visible light. Infrared radiation is not visible to the human eye but can be felt as heat. It is part of the electromagnetic spectrum, which encompasses all forms of electromagnetic radiation.
