loucy said:I think this amounts to measuring the permittivity and permeability of free space. The experiments for obtaining accurately the value of epsilon_0 and mu_0 are quite complicated. I think this is the job for people in the bureau of standards. What is the purpose of looking into this?
flatulent said:I have never heard of a case of measuring it. All of the cases I have seen have been calculating it.
flatulent said:Since impedance is the ratio of electric and magntic fields, I suspect that you would have to measure these at a point. The problem being that your measurement sensor would disturb the field. (This reminds me of the atomic physics uncertainty principle.)
