@astrid@fedi.astrid.tech @lily@glaceon.social yeah the wavelength is used to constrain chip sizes based on planned operating frequency, and therefore is an important part of very high frequency ASIC layout

@spinach@girlcock.club @astrid@fedi.astrid.tech @lily@glaceon.social it's also extremely useful for knowing when you need to switch from a lumped circuit model to a transmission line model. essentially figuring out whether the signal voltage will be near constant across the length of the trace (lumped, modelling a simplistic conductor) or if there will be considerable variation in the voltage across the length of the trace (transmission line, modelling a waveguide). and for digital it's the rise/fall time that matters, not the fundamental.
