hey mate here is ur ans :-

_______________________________

atmospheric refraction :-

The refraction of light caused by the earth's atmosphere is called atmospheric refraction.

(1) twinkling of stars :-

The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.

(2) advance sunrise and delay sunset

Atmospheric refraction affects the sunrise as it give us 2 minutes variation as well as 2 minutes late in sunset.

During sunrise, the light rays bend due to our atmosphere and we see the sun early even though the sun is just below the horizon.

Similarly, at sunset, due to the same bending of light rays, we see the apparent position of the sun, not the actual position.

hopes it's helps uh!!!!!!
