An explorer is riding his camel in the desert. Up ahead he sees what appears to be a pool of water.
He can tell if it is a real pool of water or a mirage by putting on his polarized sun glasses because:
a) The mirage is polarized and reflections from the water are not
b) Reflections from water are polarized while the mirage is not
c) Neither are polarized so one will not be able to discern a difference
d) Both are polarized so one will not be able to discern a difference
