Homework Statement
Problem: Sea water has k = 80 in the low frequency limit. Yet its refractive index is around 1.34. Explain the discrepancy
Homework Equations
For a non magnetic dielectric medium, the absolute refractive index in the low frequency range, is given by : n = √k where k = Є/ Єo is the dielectric constant of the medium. Є and Єo are the permittivities of the medium and free space, respectively.
The Attempt at a Solution
No idea. Does it have anything to do with the fact that water shows a wide variety of behaviour in various frequency ranges?
