Frequency conversions

[GeorgesOatesLarsen]

I MAJORLY suck at converting between:

• time angular frequency
• time frequency
• time angular wavelength
• time angular half wavelength
• time wavelength
• time half wavelength
• spatial angular frequency
• spatial frequency
• spatial angular wavelength
• spatial angular half wavelength
• spatial wavelength
• spatial half wavelength

Yes. All of those get used completely willy-nilly throughout physics. It would be nice to make a skill trainer for these. OML.

I suggest two variants: Equational (for the equation of conversion) Ratio (Given two frequencies of type X, what is the ratio of type Y)
