Question

Explain atmospheric refraction in detail​

Answer 1

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.

Answer 2

$\huge{\mathcal{\purple{A}\green{n}\pink{s}\blue{w}\purple{e}\green{r}\blue{⋆}}}$

Atmospheric refraction is caused by the bending of light rays when they pss through the layers of the earth's atmosphere, which are of different optical densities. ... The light coming from a star undergoes atmospheric refraction due to varying optical densities of air at various altitudes.
