It's pretty obvious that frequency is a function of time.
Velocity is a function of time. Time is also a function
of velocity. Velocity is a function of length. Length is
also a function of velocity. Go figger.

In our present use and construct of time, absolutely.

I have a bit easier "time" of "seeing" things "shorten" as velocity
increases, my feeble brain strives for even that. (waves shorten as
they are emitted by objects with velocity ...)

Still, I wonder ... and I know, that with a buck still won't even buy
you a decent cup of coffee.
