Tide said:Have you tried calculating the electron plasma frequency for some typical metals?
inha said:you wouldn't be correct. plasmon energies are several orders of magnitude lower than the x-ray range.
If you are trying to calculate the frequency at which a metal starts to become transparent to radiation, that would be the plasma frequency. Most metals are transparent at high UV frequencies.pervect said:I was wondering if it would be fair to say that the frequency at which x-rays start to penetrate a metal would be the plasma frequency associated with the electron density of the metal, i.e. the frequency given by

or whether some other mechanism was involved.
Metals are a type of element on the periodic table that are characterized by their high electrical and thermal conductivity, luster, and malleability. They are different from other elements because they have a high number of free electrons, which allows them to easily conduct electricity and heat.
X-rays are a type of electromagnetic radiation that have a shorter wavelength and higher energy than visible light. In science, they are used for imaging techniques such as X-ray crystallography to determine the structure of molecules. In medicine, they are used for diagnostic imaging to see inside the body and diagnose medical conditions.
The plasma frequency is the frequency at which electrons in a metal oscillate in response to an applied electric field. This frequency is unique for each metal and is affected by factors such as temperature and density. The behavior of metals is influenced by the plasma frequency, as it determines how easily electrons can move through the metal and how it interacts with light.
X-rays are commonly used in materials science to study the properties of metals. They can be used for techniques such as X-ray diffraction, which can reveal information about the crystal structure of a metal, and X-ray fluorescence, which can determine the elemental composition of a metal. X-ray absorption spectroscopy is also commonly used to analyze the electronic structure of metals.
Research on plasma frequency has many potential applications, including in the development of new materials with improved properties, such as increased conductivity or better light absorption. It can also be used in the design of electronic devices, as well as in the study of plasma physics and astrophysics.
