  2. Bragg's law - Wikipedia

    en.wikipedia.org/wiki/Bragg's_law

    This equation, Bragg's law, describes the condition on θ for constructive interference. [12] A map of the intensities of the scattered waves as a function of their angle is called a diffraction pattern. Strong intensities known as Bragg peaks are obtained in the diffraction pattern when the scattering angles satisfy Bragg condition.

  3. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    Scattering also includes the interaction of billiard balls on a table, the Rutherford scattering (or angle change) of alpha particles by gold nuclei, the Bragg scattering (or diffraction) of electrons and X-rays by a cluster of atoms, and the inelastic scattering of a fission fragment as it traverses a thin foil.

  4. Scatterometer - Wikipedia

    en.wikipedia.org/wiki/Scatterometer

    The scattering mechanism is known as Bragg scattering, which occurs from the waves that are in resonance with the microwaves. The backscattered power depends on the wind speed and direction. Viewed from different azimuth angles, the observed backscatter from these waves varies.

  5. Wide-angle X-ray scattering - Wikipedia

    en.wikipedia.org/wiki/Wide-angle_X-ray_scattering

    In X-ray crystallography, wide-angle X-ray scattering (WAXS) or wide-angle X-ray diffraction (WAXD) is the analysis of Bragg peaks scattered to wide angles, which (by Bragg's law) are caused by sub-nanometer-sized structures. [1] It is an X-ray-diffraction [2] method and commonly used to determine a range of information about crystalline materials.

  6. Radar angels - Wikipedia

    en.wikipedia.org/wiki/Radar_angels

    Radar angels are an effect seen on radar displays when there is a periodic structure in the view of the radar that is roughly the same length as the signal's wavelength.The angel appears to be a physically huge object on the display, often miles across, that can obscure real targets.

  7. Hegseth orders US Army to restore name of Fort Bragg - AOL

    The renaming of Fort Bragg honors all U.S. soldiers who have trained to fight and win U.S. wars, Hegseth wrote in his memo, "and is in keeping with the installation's esteemed and storied history."

  8. Acousto-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Acousto-optic_modulator

    When the incident light beam is at Bragg angle, a diffraction pattern emerges where an order of diffracted beam occurs at each angle θ that satisfies: [3] ⁡ = Here, m = ..., −2, −1, 0, +1, +2, ... is the order of diffraction, λ is the wavelength of light in vacuum, and Λ is the wavelength of the sound.

    Hegseth’s decision to name the base after Roland Bragg, not for the Confederate general, could be seen as an admission that Braxton Bragg was undeserving, said Peter Feaver, a Duke University ...
