Hi there, quick question about units.
I know wavenumber can be defined as 1/λ or 2π/λ, the latter sometimes being termed 'angular' wavenumber. Is there an agreed upon way of distinguishing between these two definitions when displaying units on, for example, a graph or paper?
I've seen units such as (m-1) which is ambiguous or (cpm) which I presume to mean cycles per metre and thus refer to angular version, but also (rad m-1).
Is there a standard that should be followed? Or is it a free for all?
Cheers,
Jesse
