← ScienceWhich mechanism reduces signal clarity when atmospheric turbulence impacts radio telescopes?
A)Wavefront distortion using atmospheric refraction✓
B)Quantum entanglement signal decoherence
C)Doppler shift from telescope motion
D)Cosmic microwave background radiation noise
💡 Explanation
Atmospheric turbulence creates variations in the refractive index; this causes wavefront distortion by unevenly slowing sections of the incoming waves. Because of uneven delay, the radio waves do NOT combine coherently causing signal blurring therefore degrades clarity of incoming signal rather than signal amplification.
