    hello,

    i am trying to get a handle on what the physical interpretation of a fourier
    transform of a general charge distribution would be.

    that is assume we have a distribution of charge in one dimension dependent
    on time p(x,t) say.

    then what would the function p(k,t) represent as it progressed in time?

    now i know that fourier transforms of charge distribution usually crop up
    when you deal with scattering angles (i.e. form factors etc) - but lets
    simply assume that
    p(x,t) is a general distribution of charge over a 'surface' for example.
    what is the physical interpretation (if any) of p(k,t)? i have my own ideas
    but most of them are not very illuminating at the moment - any other
    viewpoints
    appreciated.

    cheers
    moth
