Probably an overkill way of modelling wavelength/frequency, but allows us to model it without worrying about which to use.


The published properties would be:

  • Frequency : Hz (real)
  • Wavelength : meters (real)

  • Ucd - I think


This looks like a very simple object. Obviously we don't need to store both Frequency and Wavelength internally.

I think it makes sense for a Wave to be immutable (ie it can only be created with a set of characteristics, and thereafter is 'readonly'). The properties are all interdependent, so changing one without the other does not make sense.
