## Light Pollution and Contrast
Light pollution raises the sky background, drowning out faint objects.
### Key Relation
The flux ratio of sky to object is:
**ratio = 10^((mag_obj - mag_sky) / 2.5)**
A higher ratio means the sky overwhelms the target. Object contrast is approximately 1 / (1 + ratio).
Darker skies (higher mag/arcsec2) dramatically improve contrast for faint targets.

हल किया गया उदाहरण
Sky = 19 mag/arcsec2 (suburban), object = 22 mag/arcsec2.
- ratio = 10^((22 - 19) / 2.5)
- ratio = 10^1.2 = 15.85
- contrast = 100 / (1 + 15.85) = 5.94%
- The object has only 5.9% contrast against the bright sky.
