  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. Acousto-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Acousto-optic_modulator

    An acousto-optic modulator (AOM), also called a Bragg cell or an acousto-optic deflector (AOD), uses the acousto-optic effect to diffract and shift the frequency of light using sound waves (usually at radio-frequency). They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control.

  4. Hicks equation - Wikipedia

    en.wikipedia.org/wiki/Hicks_equation

    In fluid dynamics, Hicks equation, sometimes also referred as Bragg–Hawthorne equation or Squire–Long equation, is a partial differential equation that describes the distribution of stream function for axisymmetric inviscid fluid, named after William Mitchinson Hicks, who derived it first in 1898.

  5. Distributed Bragg reflector - Wikipedia

    en.wikipedia.org/wiki/Distributed_Bragg_reflector

    Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...

  6. X-ray diffraction - Wikipedia

    en.wikipedia.org/wiki/X-ray_diffraction

    William Lawrence Bragg proposed a model where the incoming X-rays are scattered specularly (mirror-like) from each plane; from that assumption, X-rays scattered from adjacent planes will combine constructively (constructive interference) when the angle θ between the plane and the X-ray results in a path-length difference that is an integer ...

  7. Bragg–Gray cavity theory - Wikipedia

    en.wikipedia.org/wiki/Bragg–Gray_cavity_theory

    Bragg–Gray cavity theory relates the radiation dose in a cavity volume of material to the dose that would exist in a surrounding medium in the absence of the cavity volume. It was developed in 1936 by British scientists Louis Harold Gray , William Henry Bragg , and William Lawrence Bragg .

  8. William Henry Bragg - Wikipedia

    en.wikipedia.org/wiki/William_Henry_Bragg

    Sir William Henry Bragg (2 July 1862 – 12 March 1942) was an English physicist, chemist, mathematician, and active sportsman who uniquely [1] shared a Nobel Prize with his son Lawrence Bragg – the 1915 Nobel Prize in Physics: "for their services in the analysis of crystal structure by means of X-rays".
