This frequency is relevant ONLY for vacuum (or with a very, very
slight alteration) air.
Now, it may seem that all air is air, but no. There are slight
variations here too that on the global scale small shifts make large
changes. Those small shifts are accounted for by pressure, water
content (vapor), and temperature.

Same thing happens with light through water, the light slows down but
doesnt change in color(frequency).
