My questions is about the conversion of a range of wavelengths in Hz, such as for an optical filter, in a medium different from air. Since the refractive index n is higher than 1, (let's say n=1.5) and than the value of c is almost 2x108 m/s, also the equation in the link below has to be corrected?

When light is propagating in a different medium than air, is it also necessary to modify accordingly the equations for a Fabry-Perot etalon and similar filters?
Thanks a lot!
