what is the phenomenon behind the twinkling of stars in the sky
Answers
Answer:
The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. This means that some of the light reaches us directly and some gets bent slightly away.
Answer:
Stars are have self luminous and can be seen at night.
As the density of air increase with lowering height above the surface of the Earth , the refractive index also increase.
star light coming towards us travel from Rara medium to Denser medium and bend towards the Normal.
This makes its actual position .
The apparent position of star keeps changing a bit this is because of changing atmosphere and density.
because of this brightness of star keep Changing and star appears to be twinkling.....
