    Hi,

    My homework is to write a method to investigate the hypothesis "the greater the concentration of salt water solution the greater the refractive index".

    The first question is to research the likely concentrations which will give a measurable effect on the refractive index.

    The last question is " using research about salt concentrations in oceans and seas whether the effect described by the hypothesis is likely to be noticeable in swimming pools".

    Please could someone help as I've been looking for ages and I can't find anything very useful.

    Thanks

    Didn't read it all, but does this link help?

    Try to compare the salt concentration of ocean water with that of pool water
