Document Summary

By the end of this unit, you should be able to: Unit 4: electromagnetic radiation and the greenhouse effect. List the names, approximate wavelengths and frequencies of the various regions of the em spectrum. Explain the meaning of blackbody and how it relates to the temperature and physical makeup of an object. Describe the effect that temperature has on the blackbody emissions of an object. Explain the mechanism of the greenhouse effect and how it is involved in the energy of the earth. A. the electromagnetic spectrum and the inverse square law. Third method of heat transfer is radiation - other two are conduction and convection. While conduction and convection require the intermediary of matter to transport energy, radiation does not. Energy of the sun comes to us by the process of radiation through essentially empty space. As waves they are characterized by a wavelength ( ) and frequency ( ) Wavelength - the crest to crest distance of the waves.
