What does the word apparent mean in apparent visual magnitude?
What the word “apparent” means in “apparent visual magnitude”.
Introduction:
Astronomers of the old have classified stars using a magnitude scale, which describes the brightness of a star as seen from the Earth. The modern system of gauging the brightness of a star is an improved version of the old magnitude scale.
Intensity of light received from a star is inversely proportional to the square of its distance from the star. Therefore, farther the star is, fainter it would appear to us. The magnitude scale ranks the brightness of stars as they are seen from the earth...
