What is an non-example of absolute brightness?
Anything that is not the measure of intrinsic brightness of a celestial object.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.

What factor affects the absolute brightness of a star?
Energy output, as absolute brightness (magnitude) is taken at a standard distance of 10 parsecs.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
