WebFig. 2.4. Basic interactions between electromagnetic energy and an earth surface. (Source: Lillesand, Kiefer, 2002) In above equation two points concerning this relationship should be noted. First, the proportions of energy reflected, absorbed, and transmitted will vary for different earth features, depending on their material type and condition. WebElectromagnetic radiation (EMR) is generated on the hot surface of the sun and carries solar energy through the space to the earth. The phenomenon of EMR can be explained by two physical theories at the same time: the wave theory and the quantum theory. EMR can be seen as a wave with time-varying electric (E) and magnetic fields (B). safe aed in pregnancy https://pauliz4life.net

Web2) spectral. The first class tells us how EMR is affected by the distance between source and receiver, and by their relative sizes and orientations. The second group of descriptions tells us how the intensity of EMR depends on ν (or λ). This is important since most natural EMR sources have very broad power spectra. 1) geometry and EMR WebJan 1, 1987 · Light and thermal energy are examples of EMR. In addition to by radiation, thermal energy may travel by conduction and convection. In this chapter, the physical concepts of EMR and its interaction with the atmosphere and objects at the earth's surface are discussed.
