[edit] Opposition to transmission

Electrical impedances can be described as an opposition to the passage of current. However, you cannot say that impedances of vacuum or of a medium are an opposition to the transmission of waves. Waves are very well transmitted in high impedance media. Just the speed of waves and the ratios of some physical quantities are different (electric/magnetic fields, pressure/displacement, etc.). -- LPFR 08:48, 6 November 2006 (UTC)
