  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. Radio acoustic sounding system - Wikipedia

    en.wikipedia.org/wiki/Radio_acoustic_sounding_system

    The principle of operation behind RASS is as follows: Bragg scattering occurs when acoustic energy (i.e., sound) is transmitted into the vertical beam of a radar such that the wavelength of the acoustic signal matches the half-wavelength of the radar. As the frequency of the acoustic signal is varied, strongly enhanced scattering of the radar ...

  4. 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.

  5. 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. [4]

  6. X-ray crystal truncation rod - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystal_truncation_rod

    X-ray crystal truncation rod scattering is a powerful method in surface science, based on analysis of surface X-ray diffraction (SXRD) patterns from a crystalline surface. For an infinite crystal , the diffracted pattern is concentrated in Dirac delta function like Bragg peaks .

  7. 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.

  9. Bragg plane - Wikipedia

    en.wikipedia.org/wiki/Bragg_plane

    In physics, a Bragg plane is a plane in reciprocal space which bisects a reciprocal lattice vector, , at right angles. [1] The Bragg plane is defined as part of the Von Laue condition for diffraction peaks in x-ray diffraction crystallography .
