Clear formula for water penetration by wave frequency

Click For Summary
SUMMARY

The discussion centers on the need for a straightforward formula to determine water penetration by radio wave frequency, specifically for both clear and salty water. Participants highlight the complexity of existing formulas and suggest that empirical formulas may only provide limited accuracy across specific frequency ranges. A reference to RF propagation versus salinity is provided, along with a mention of the Beer-Lambert law for visual frequencies. The conversation emphasizes the importance of defining the required accuracy and frequency range for effective application.

PREREQUISITES
  • Understanding of radio wave propagation principles
  • Familiarity with empirical formulas and their limitations
  • Knowledge of the Beer-Lambert law for absorption coefficients
  • Basic concepts of salinity's effect on wave behavior
NEXT STEPS
  • Research RF propagation models specific to saline environments
  • Explore empirical formulas for radio wave penetration in water
  • Study the Beer-Lambert law and its applications in wave absorption
  • Investigate accuracy requirements for different frequency ranges in wave propagation
USEFUL FOR

Researchers, engineers, and professionals involved in telecommunications, environmental science, and anyone interested in the effects of salinity on radio wave propagation.

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.
