I hope it's helpful

Explanation:

Light waves traveling through Earth's atmosphere diffract as they pass through pockets of air at different temperatures. Because the light waves come from a single point, this effect can make the star's brightness and/or position appear to change.

Answer 2

The reason for the twinkling of stars and the change in position is due to the refraction of starlight.

• The density of atmospheric air varies within different layers.
• When starlight travels through the different layers of the atmosphere, the starlight gets refracted many times.
• So the light is reaching our eyes after multiple refractions.
• As the atmosphere moves there will be a corresponding shift in the light from the stars.
• Hence the image of stars shifts in our eyes continuously.
• This is the reason for the twinkling of stars and the change in position when viewed through a telescope.
