Explanation:
Detailed explanation-1: -When I say apparent brightness, I mean how bright the star appears to a detector here on Earth. The luminosity of a star, on the other hand, is the amount of light it emits from its surface. The difference between luminosity and apparent brightness depends on distance.
Detailed explanation-2: -b = apparent brightness of the star (in watts/meter2) L = luminosity of the star (in watts) d = distance to the star (in meters) pi = approximately 3.14159265 (but you knew that already) 14-Jan-2020
