Question

define atmospheric refraction

Answer 1

Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through theatmosphere due to the variation in air density as a function of height. ... Astronomical or celestial refractioncauses astronomical objects to appear higher in the sky than they are in reality.

Answer 2

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

When the sun rays passing through the atmosphere suffer refraction known as atmospheric refraction.

It is caused by the difference is the dinsities of air in the differnt layes of the atmosphere.

Atmospheric refraction is a change in the refractive index of light waves or rays due to differences in elevation in atmospheric density.
