ROY G. BIV List the abbreviated
colors Visible spectrum is
the colors your eye can detect
Red is the first color on the left, with a large wavelength and a low frequency
Violet is opposite red
Animation
Here is an animation to help you understand what really happens.

Black Body Effect
1. Earth absorbs most radiation.Its temperature is based on the amount of
radiation it absorbs.Blackbody effect is
both absorption and the resulting emission.
The black body's temperature affects the intensity of emission.Earth then releases infrared rays back into space.
Albedo
The reflectivity of any substance the albedo.The albedo for Earth is roughly about 0.28; 0.28 is a ratio, has no units.
Albedo reflects the sun's light back to the atmosphere and most of the time back to space.
Greenhouse GasesAlthough many people think
that the Greenhouse effect is harming the environment, it is actually essential for the survival of life on Earth. The Greenhouse effect keeps water at a liquid temperature and maintains the Earth at a warm and stable temperature for its inhabitants.
Experiment

GWP is how much these gases can heat up the Earth.
The GWP over 100 years for SO2 is .019891
For CH4, the GWP is 7.24002
The GWP for CF3CH2F is 466.0454
Carbon Dioxide Stretches
Symmetric, Asymmetric, and bend.
Asymmetric stretches are IR active.
Kyoto Protocol
The Kyoto Protocol was made in Japan, in 1997. It is an agreement signed by many countries and industrialized nations to commit to cutting Greenhouse gasses to 5% below the 1990 levels.
