Unformatted text preview: Amount of energy in an electromagnetic wave that passes perpendicularly through a unit surface area/ unit time Inverse square law Rate at which solar flux decreases with increasing distance Blackbody : something that emits or absorbs electromagnetic radiation with 100% efficiency at all wavelengths Blackbody radiation: radiation emitted by a blackbody, characteristic wavelength distribution that depends on bodys absolute temp. Wiens law: states that flux of radiation emitted by a blackbody reaches its peak value at a wavelength which depends inversely on bodys absolute temp. Photosphere: surface layer where sun emits most of its energy StefanBoltzmann law: states that the energy flux emitted by a blackbody is related to the fourth power of the bodys absolute temp....
