Answer:

It is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. ... Astronomical or celestial refraction causes astronomical objects to appear higher above the horizon than they actually are.

AnswEr :-

Atmospheric refraction is the change in the direction of propagation of electromagnetic radiation or sound waves in traversing the atmosphere.

Such changes are caused by gradients in the density of the air.

Example ,

Twinkling of stars: Stars twinkle on account of atmospheric refraction. It occurs because there is a gradual increase in the refractive index from the atmosphere to the earth's surface. Thus, the apparent position of the star is different from the actual position.
