SOLVED: (b) Show that the skin depth in a good conductor (Î´) is Î»/2 (where Î» is the wavelength in the conductor). Find the skin depth (in nanometers) for a typical metal (Ïƒ 10^7(Î©m)^-1) in the visible range (Ï‰ 10^15/s), assuming Îµ = Îµo and Î¼ = Î¼o. Why are metals opaque?1/2-K= Îµo = 8.01 x 10^-12 Table 4.2 For pure water, Îµ = Îµo(1 Xm) = Îµo(1 - 9.01 x 10^-6) = 1/2.51 Table 7.1(t < 1/Ï‰); Î´ = 1

SOLVED: In an experiment to observe the X-ray wavelengths of silver, a thin sample of silver metal is bombarded with energetic electrons and an X-ray spectrum similar to that of Figure 8.15 is produced. The measured wavelengths in nm are 0.0487,0.0497,0.0561,0.370,0.438, and 2.38 . Using these wavelengths determine the energy levels and draw them to scale for silver in the style of Figure 8.14 . Label each level with its energy and principal quantum number. Label the six X-ray transitions with t

A measure of the density of the free-electron gas in a metal is the distance rs, which is defined as the radius of the sphere whose volume equals the volume per conduction electron. (a) Show that rs=(3 / 4 πna), where na is the free-electron number density. (b) Calculate rs for copper in nanometers. | Numerade
