Question

what happens to the star light coming from outer space when it enters the earth's atmosphere? what is its effect on stars position? plz help anyone.....​

Answer 1

Answer:

Random refraction effects

Turbulence in Earth's atmosphere scatters the light from stars, making them appear brighter and fainter on a time-scale of milliseconds. The slowest components of these fluctuations are visible as twinkling (also called scintillation).

Electromagnetic waves entering Earth's atmosphere from space are bent by refraction. Atmospheric refraction is greatest for signals near the horizon where they come in at the lowest angle. The apparent altitude of the signal source can be on the order of half a degree higher than its true height.

Turbulence in Earth's atmosphere scatters the light from stars, making them appear brighter and fainter on a time-scale of milliseconds. The slowest components of these fluctuations are visible as twinkling . Electromagnetic waves entering Earth's atmosphere from space are bent by refraction.
