Answer 1

Why do stars twinkle?

When a ray of light travels from one medium to another it ‘bends’. This phenomenon is referred to as refraction. If it travels from a rare medium to a dense medium, it bends towards the normal and if it travels from a dense medium to a rarer medium, it bends away from the normal. The speed through which it travels changes depending on the medium and therefore this bending occurs.

Answer 2

Answer:

The movement of air 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 . To our eyes , this makes the star seem to twinkle
