← ScienceWhich distortion compromises telescope image resolution during prolonged observations?
A)Atmospheric turbulence induces speckle patterns✓
B)Mirror surface oxidization increases reflectance
C)Internal stresses causes thermal expansion
D)Vibration induces chromatic aberration shifts
💡 Explanation
Atmospheric turbulence causes image distortion because variations in air density lead to differing refractive indices; therefore, constructive and destructive interference create speckle patterns degrading resolution rather than other distortions from mechanical effects.
