    The shape is definitely going to depend on the index of refraction of the material it is made out of.

    Welcome to the PF.

    When I go a Google search on the title of your thread, the first non-advertisement link is this one for wikipedia. It looks to have what you need (as long as you know the index of refraction of your material, as already pointed out)... :smile:
