2301nsc Electromagnetism And Optics Show That The Skin Depth For Cu At 5 1015 Hz Mid 4081464
(i) Show that the skin depth for Cu at 5×1015 Hz (middle of the visible light band) isapproximately 1 nm, compared to 10 mm at 50 Hz (AC mains frequency). (4 marks)(ii) Show that for Cu the limit s e? ? corresponds to 18 f 010 Hz , meaning that thisapproximation applies at frequencies up […]
