Question

atmospheric refraction.....​

Answer 1

$\huge\frak{AnsWER}$

$\large\underline\bold\red{Atmospheric\: refraction:-}$

Due to the continuous variation in the density and temperature in the different layers of the earth's atmosphere , these layers will acts as a different medium

is known as atmospheric refraction

Example : -

i) Twinkling of stars

ii) Advance sunrise and delayed sunset

Answer 2

Explanation:

Question:-

What is Atmospheric Refraction?

_________________________

Answer

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.
