← ScienceWhich outcome occurs when turbulence induces variations in atmospheric density across a telescope's light path?
A)Speckle patterns form in images✓
B)Chromatic aberration reduces resolution
C)Focal length of scope increases
D)Light phase becomes universally inverted
💡 Explanation
Speckle patterns form because atmospheric turbulence introduces phase differences causing constructive and destructive wave interference from different regions of the distorted wavefront; therefore this occurs rather than changing focal length, because speckle is due to interference.
