Question

give scientific reason we can see the sun when it is little below the horizon​

Answer 1

Answer:

Because of the refraction of the light. from the Sun by the Earth's atmosphere--the Earth's atmosphere bends the path of the light so that we see the Sun in a position slightly different from where it really is.

Answer 2

Explanation:

Atmospheric refraction causes the Sun to be seen while it is still below the horizon. Light from the lower edge of the Sun's disk is refracted more than light from the upper edge. This reduces the apparent height of the Sun when it appears just above the horizon.
