The 27 pages that link to Mean free path, each with the reason it gives.

• Optical depthCompared with: It is a local length scale; optical depth accumulates interaction probability along a path.

• Debye lengthCompared with: It is a collisional transport scale, unlike the electrostatic screening scale.

• Compton wavelengthCompared with: It is set by interactions with a medium, whereas the Compton wavelength is determined by particle mass.
