Question

The sun near the Horizon appears flattened at the sunset and sunrise explain why

Answer 1

The sun near horizon appears flattened at sunrise and sunset. This is because the light from the sun suffers multiple retractions in air before reaching us hence the apparent position of the sun is different from its actual position. Hence it appears to be flattened.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow}{Answer }}$

1. The earth is surrounded by an atmosphere which is denser near the surface of the earth.

2. When the rays of light from the Sun enter the earth's atmosphere from outer space, they travel from a rarer medium to a denser medium.

3. Hence, they bend towards the normal on refraction.

4. Hence, even when th sun is below the horizon while rising or setting, its rays reach is due to refraction and it appears to be on the horizon.

Therefore, the sun near the horizon appears flattened at the sunrise and sunset.
