Clear formula for water penetration by wave frequency

Click For Summary

Discussion Overview

The discussion revolves around the search for a clear formula that describes the penetration of radio waves in both clear and salty water, with a focus on simplifying existing complex formulas found online. The inquiry touches on theoretical aspects of wave propagation in different mediums.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests a simple formula for radio wave penetration in water, expressing frustration with the complexity of existing formulas.
  • Another participant questions the type of wave being discussed, clarifying that the focus is on radio waves.
  • A suggestion is made that clear formulas may not be feasible, and a link to a resource is provided for potential data extraction.
  • One participant shares a search link related to RF propagation and salinity, inviting further specific questions about the results.
  • Another participant notes that accuracy is a concern, mentioning that clear formulas are often empirical and may only be accurate within a limited range of frequencies. They reference the Beer-Lambert law for visual frequencies as a method used in their work.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the availability of a clear formula, and multiple perspectives on the complexity and accuracy of existing formulas are presented. The discussion remains unresolved regarding the specific formula sought.

Contextual Notes

Limitations include the potential dependency on specific frequency ranges and the empirical nature of suggested formulas, which may not apply universally.

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.
