Question

explain any two effects of atmospheric refraction observer on the earth​

Answer 1

Explanation:

An observer on the earth sees the sun two minutes before the sun reaches the horizon. A ray of sunlight entering the earth's atmosphere follows a curved path due to atmospheric refraction before reaching the earth. ... Tyndall effect can be observed when sunlight passes through the canopy of a dense forest.

Answer 2

Answer:

~The atmosphere of Earth is not evenly distributed, it is optically and molecularly denser at the bottom and and becomes rarer as we up, so the velocity of light changes from layer to layer. ... These factors form differnt layers of air with different optical densities and thus cause the atmospheric refration.~
