what is atmospheric refraction ?

Answers

Answered by krish9583

Answer:

Atmospheric refraction 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. This refraction is due to the velocity of light through air decreasing with increased density.

Answered by jaiswalkshitij456

Atmospheric refraction is the refraction of light caused by the earth's atmosphere due to change in the refractive indices of different layers of the atmosphere. Thus, apparent position of the star fluctuates and the amount of star light entering the eye flickers giving the twinkling effect.
