Radiation Absorption

Click on a Dinitrogen molecule (from Non Greenhouse Gases in the right-hand bar), then click on the two circular boxes on the left to insert it twice. Similarly, insert a Dioxygen molecule in a single box, then anArgon molecule in the last box.

Then activate Visible Light (top of right-hand bar) and click on Play to view visible radiation from the Sun (short wavelengths).

Then activate Infrared to view radiation emitted by the Earth's surface (long wavelengths).
