Flux and LuminosityFlux and LuminosityA brief interludeA brief interlude

• Luminosity is a measure of the amount of light RELEASED from a source

• Flux is a measure of the amount of light that REACHES Earth• So two objects of equal luminosity may have different fluxes• We need to know the distance to a source to calculate the
