Explanation:
The twinkling of stars is an optical phenomenon that occurs due to atmospheric refraction. The light coming from the stars passes through the layers of the Earth's atmosphere, which has varying densities. This causes the light to bend or refract at different angles, making the stars appear to twinkle or flicker.
Atmospheric Refraction:
Atmospheric refraction occurs when light passes through a medium of varying densities. The Earth's atmosphere has different layers of gases, each with a different density. When light passes through these layers, it bends or refracts due to the change in density. The amount of refraction depends on the angle at which the light enters the atmosphere. The lower the angle, the more the light is refracted.
Twinkling of Stars:
The twinkling of stars occurs because stars are very far away from the Earth and their light has to pass through a lot of atmosphere before reaching our eyes. As the light passes through the different layers of the atmosphere, it gets refracted in different directions. This causes the light to scatter, making the stars appear to twinkle or flicker.
Conclusion:
In conclusion, the twinkling of stars is due to atmospheric refraction. The light from the stars passes through the Earth's atmosphere and gets refracted in different directions, causing the stars to twinkle. This phenomenon can be observed on clear nights when the atmosphere is not turbulent.

The refraction of light induced by the earth's atmosphere is known as atmospheric refraction. Atmospheric refraction occurs because the different layers of the earth's atmosphere vary in terms of optical densities. It is caused by the varied optical densities of the earth's atmosphere layers.
