Another way to understand and measure an object's brightness is through its magnitude. It's a useful thing to know if you're stargazing since it helps you understand how observers can refer to stars' brightnesses with respect to each other. The magnitude number takes into account an object's luminosity … See more Most people can get a very general idea of an object's luminosity simply by looking at it. If it appears bright, it has a higher luminosity than if it's dim. However, that appearance can be … See more In most cases, luminosity is meant to relate how much energy is being emitted by an object in all the forms of light it radiates (visual, infrared, x-ray, etc.). Luminosity is the term that we apply to all wavelengths, … See more WebMar 9, 2016 · If the object has a measured flux F then its luminosity is given by L = 4*pi*F* (cz/H o) 2 and thus the mass-to-luminosity ratio of the object is M/L = (H o /cz)*theta*v 2 / (4*pi*F*G) If N objects of this mass are seen in the surveyed volume, then the derived density of the Universe is given by
