The energy output of the Sun
December 3, 2009 3:26 am HomeScientists have shown that the output of the Sun is temporally variable. This of course is not entirely true. Scientists have shown that the output of the Sun can be considered constant. For general purposes, the energy output of the Sun can be considered constant. At three times the distance, the intensity will become only one-ninth of its original intensity at a distance of one unit, and so on. As a result of this law, if the intensity of earth4energy radiation at a given distance is one unit, at twice the distance the intensity will become only one-quarter. This law merely states that the intensity of the radiation emitted from the Sun varies with the squared distance from the source. The intensity of solar radiation striking these objects is determined by a physical law known as the Inverse Square Law.
