Question

what is atmospheric refraction.​

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. ... Astronomical or celestial refraction causes astronomical objects to appear higher above the horizon than they actually are.

Answer 2

${\bold{\blue{\underline{\red{A}\pink{ns}\green{we}\purple{r:-}}}}}$

➝ The refraction of light caused by the earth's atmosphere having air layers of varying optical densities is called atmospheric refraction.

⚪ The air in the upper atmosphere is optically rarer and as we come down,the air in the lower atmosphere is optically denser.

⚪ When light rays pass through the atmosphere having air layers of different optical densities,then refraction of light take place.

✴️ Related to refraction of light :-

➝ The refraction or bending of light takes place at the boundary between the two media.

➝ The angle between Incident ray and normal ray at the point of incidence is called the angle of incidence.

➝ The angle between the refracted ray and the normal at the point of incidence is called the angle of refraction
