@Efi @chr@cybre.space I don't know that I follow
@Efi @chr@cybre.space I can handle technical!
Would it not have any difference with wavelength? I feel like it would, because I know for a fact that x-rays can penetrate much further
@Efi @chr@cybre.space there's no dispersion at all? and no nonlinearity at all? this has the feel of over-idealized stuff to me
@Efi @chr@cybre.space there are nonlinear optical materials used for things like optical amplifiers though, I know that
@Efi @chr@cybre.space are we talking about a physical, measured quantity or something in computer graphics, anyway?
