Which statement describes absolute and apparent brightness?

Sagot :

NOTES TO TAKE DOWN:

Apparent brightness is a human measurement, and it would change for each star if the measurement were taken from another location. The more precise counterpart of apparent brightness is called absolute brightness (or absolute magnitude) and is the measure of the luminosity of a star, but on a common scale.

ANSWER:

Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer.
