  2. X: The Man with the X-ray Eyes - Wikipedia

    en.wikipedia.org/wiki/X:_The_Man_with_the_X-ray_Eyes

    At the film review aggregator website Rotten Tomatoes, the film holds an approval rating of 88%, based on 25 reviews, with a weighted average rating of 6.6/10. The site's critical consensus reads, "By turns lurid and disturbing, The Man with the X-Ray Eyes is a compelling piece of sci-fi pulp and one of Roger Corman's most effective movies." [7]

  3. X-ray - Wikipedia

    en.wikipedia.org/wiki/X-ray

    X-rays with high photon energies above 5–10 keV (below 0.2–0.1 nm wavelength) are called hard X-rays, while those with lower energy (and longer wavelength) are called soft X-rays. [71] The intermediate range with photon energies of several keV is often referred to as tender X-rays.

  4. X-ray filter - Wikipedia

    en.wikipedia.org/wiki/X-ray_filter

    X-ray filter. An X-ray filter (or compensating filter) is a device placed in front of an X-ray source in order to reduce the intensity of particular wavelengths from its spectrum and selectively alter the distribution of X-ray wavelengths within a given beam before reaching the image receptor. [1] Adding a filtration device to certain x-ray ...

  5. X-ray background - Wikipedia

    en.wikipedia.org/wiki/X-ray_background

    The observed X-ray background is thought to result from, at the "soft" end (below 0.3 keV), galactic X-ray emission, the "galactic" X-ray background, and, at the "hard" end (above 0.3keV), from a combination of many unresolved X-ray sources outside of the Milky Way, the "cosmic" X-ray background (CXB). The galactic X-ray background is produced ...

    en.wikipedia.org/wiki/X-ray_absorption_near_edge...

    X-ray absorption near edge structure (XANES), also known as near edge X-ray absorption fine structure (NEXAFS), is a type of absorption spectroscopy that indicates the features in the X-ray absorption spectra of condensed matter due to the photoabsorption cross section for electronic transitions from an atomic core level to final states in the energy region of 50–100 eV above the selected ...

  7. Chandra X-ray Observatory - Wikipedia

    en.wikipedia.org/wiki/Chandra_X-ray_Observatory

    The Chandra X-ray Observatory ( CXO ), previously known as the Advanced X-ray Astrophysics Facility ( AXAF ), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999. Chandra was sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high ...

  8. X-ray specs - Wikipedia

    en.wikipedia.org/wiki/X-ray_specs

    X-ray specs. X-ray specs or X-ray glasses are an American novelty item, purported to allow users to see through or into solid objects. In reality, the spectacles merely create an optical illusion; no X-rays are involved. The current paper version is sold under the name "X-Ray Spex"; a similar product is sold under the name "X-Ray Gogs".

  9. X-ray emission spectroscopy - Wikipedia

    en.wikipedia.org/wiki/X-ray_emission_spectroscopy

    X-ray emission spectroscopy. X-ray emission spectroscopy ( XES) is a form of X-ray spectroscopy in which a core electron is excited by an incident x-ray photon and then this excited state decays by emitting an x-ray photon to fill the core hole. The energy of the emitted photon is the energy difference between the involved electronic levels.
