I Clear formula for water penetration by wave frequency

  1. Dec 7, 2018 at 11:24 AM #1
    I want a clear formula for clear water (and salty water) penetration by giving only the radio wave frequency .
    I searched the web , the formulas on the web are so complicated .
    Are there any simple formula available for that ?

    Not my field but what sort of wave? Light? Sound? Radio? Mexican?

    I mean radio wave

    I don't think that's a serious possibility. Could this link be of any help? You could extract some data from the graphs from this golden oldie. (I loved the kMC/s for GHz)

    Another aspect is accuracy I presume. Neat clear formulas tends to be empirical in nature which typically only are fairly accurate over a limited set of input frequencies. So what level of accuracy you need/want and over what range of inputs matter a lot too.

    For visual frequencies I've used https://en.wikipedia.org/wiki/Beer–Lambert_law along with measured absorption coefficients (interpolated). But my work was just for rendering, not absolute accuracy.
