The Inverse-Square Law

Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time. In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical objects. In SI units, luminosity is measured in joules per second, or watts. In astronomy, values for luminosity are often given in the terms of the luminosity of the Sun, L⊙. Luminosity can also be given in term… WebA star’s intrinsic brightness, or luminosity, is related to a star’s apparent brightness through the inverse square law and a normalization. By convention, this relation is B b = r 10 pc 2; where B is the absolute brightness.
