Is this an acceptable approach to path-analysis / SEM?

I want to test a model in which all possible paths between variables are captured (see fig 1) and then upon reviewing the path coefficients, remove non-significant paths (fig 2). Obviously with...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
