But the greenhouse gas molecules absorb the infrared light, and then re-radiate some of it back to the Earth's surface. This makes the surface hotter so it radiates more light, thus establishing an equilibrium at a higher temperature. This process is known as the Greenhouse Effect.Jul 25, 2007

Do greenhouse gases interact with infrared light?

Greenhouse Gases. You have already learned that Earth's atmosphere is composed primarily of nitrogen and oxygen. These gases are transparent to incoming solar radiation. They are also transparent to outgoing infrared radiation, which means that they do not absorb or emit solar or infrared radiation.

How do greenhouse gases affect visible and infrared light?

Greenhouse gases in the atmosphere (methane, carbon dioxide, etc.) let visible light pass through, but absorb infrared light – causing the atmosphere to heat up. The warmer atmosphere emits more infrared light, which tends to be re-absorbed – perhaps many times – before the energy eventually returns to space.

How does infrared light interact with the atmosphere?

Earth scientists study infrared as the thermal emission (or heat) from our planet. As incident solar radiation hits Earth, some of this energy is absorbed by the atmosphere and the surface, thereby warming the planet. This heat is emitted from Earth in the form of infrared radiation.

Do greenhouse gasses trap infrared?

And importantly, greenhouse gases don't absorb all photons that cross their paths. Instead, they mostly take in photons leaving the Earth for space. “CO2 molecules absorb infrared light at a few wavelengths, but the most important absorption is light of about 15 microns,” says Kroll.

What are the two greenhouse gases most responsible for absorbing infrared light?

Water and carbon dioxide are gases that absorb and emit infrared light. These gases are transparent to visible light and absorb and give off infrared light.

Do greenhouse gases absorb visible light?

You can see that both gases do not absorb at wavelengths in the visible light spectrum. Water is a little bit more confusing because liquid water absorbs different bands than water vapor. Also, water vapor does absorb a small amount of visible light.

How do greenhouse gases affect visible and infrared light quizlet?

Greenhouse gases transmit visible light, allowing it to heat the surface, but then absorb infrared light from Earth, trapping the heat near the surface. Greenhouse gases absorb infrared light from the Sun, which then heats the atmosphere and the surface.

Do greenhouse gases affect visible light?

They do not effect visible light but they absorb infrared light.

How do gases and particles in the atmosphere interact with light rays?

Particles and gases in the atmosphere can affect the incoming light and radiation. These effects are caused by the mechanisms of scattering and absorption.
