Question

Explain atmospheric refraction

Answer 1

The angular difference between the apparent zenith distance of a celestial body and its true zenith distance, produced by refraction effectsas the light from the body penetrates the atmosphere.Any refraction caused by the atmosphere's normal decrease in density with height.

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.
