Document Summary
In the first part of this lab we will investigate radiation laws and learn how they apply to the earth as a planet, while the second part will explore the influence on this by the greenhouse effect. We will study dependence of energy flux on the distance from the point source. We also will discuss characteristics of an ideal blackbody and concepts of albedo, absorbed and radiated energies and how these combine to produce the effective planet temperature. Finally we will address how greenhouse gases affect this value. One of the ways to transfer energy from one body to another is through radiation or, more precisely, electromagnetic radiation. Unlike in the case of conduction and convection, electromagnetic radiation does not require direct contact of the bodies or the presence of a medium between them. Electromagnetic radiation is a propagating wave that has alternating electric and magnetic components.
