1)Due to change in the density of the air refraction takes place.
2)The sunlight bends towards the normal from rarer medium to denser medium.
3)This takes place again and again, so sunlight has to travel curve path.
4)The sun is near to horizon at the time of sunrise ,hence has to travel longer path.
5)Therefore,its two minutes earlier the sunrise that we see sun.
Similarly,
delayed sunset can be explained .
