उत्तर
We can see the Sun even when it is little below the horizon because of refraction of light.
Explanation:
We can see the Sun even when it is a little below the horizon because of atmospheric refraction. The Earth’s atmosphere bends the light from the Sun upwards towards the eye of the observer. Even though the Sun itself might be just below the horizon line, the light is refracted or bent by the atmosphere, thus making the Sun appear to be visible.
