(ii) When the Sun is somewhat below the horizon, its light rays are able to reach us along a curved path due to the refraction through Earth's atmosphere.
(iii) Thus we see the Sun even before it emerges above the horizon.
(iv) Samething happens at the time of sunset, we keep seeing the Sun for a short while even after it goes below horizon.
