The light from a flashlight can be used to model the apparent magnitude of two stars with the same absolute magnitude by demonstrating how distance affects brightness. Just as a flashlight's light diminishes with distance, the apparent brightness of a star decreases as it moves farther away from an observer. If two stars have the same absolute magnitude but are at different distances, the one closer will appear brighter (higher apparent magnitude) than the one farther away. This relationship illustrates how apparent magnitude depends not only on intrinsic brightness but also on distance from the observer.

How does apparent magnitude of a star differ from absolute magnitude?

Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.


What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?

The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
