Assignment:
Questions:
1. In what spectral region does the major wavelength emitted from the Sun appear? [Choices: radio, microwave, infrared, visible, ultraviolet, X-ray, gamma ray.]
2. In what spectral region does the major wavelength emitted from the earth appear?
3. Does it seem reasonable that the earth's atmosphere will allow the solar radiation to pass?
4. Does it seem reasonable that the earth's atmosphere will allow the blackbody radiation due earth's temperature to pass?
5. What atmospheric gases will absorb infrared light? (These are sometimes called "Greenhouse Gases".)
6. Sunlight carries energy which gets absorbed by the earth. Infrared light also carries energy back out into space from the earth. If gases in the atmosphere absorb more infrared light before the light can leave the atmosphere, what does conservation of energy say should change about the gases that absorb the energy?
7. What does this indicate is a likely outcome if the amount of greenhouse gases in the atmosphere increases? [See Section 8.7b, pp. 317-319 for data.]
