If I stand on the beach and look out towards 
the horizon, what is the maximum distance I 
am looking at? Why is the optical horizon 
greater than the geometric horizon? Is the 
optical horizon approximately 12 km [as past 
bushwalking experience suggests] and does 
this vary over water compared to land?
