Which phenomenon impairs telescope image clarity because of atmospheric variation?

💡 Explanation

Seeing degrades images because random temperature differences cause small-scale refractive index gradients. These gradients lead to varying optical path differences; consequently, destructive **interference** blurs light received from a far object, therefore image quality decreases rather than being absorbed or affected by chromatic issues.
