  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. 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 ...

  4. Wave interference - Wikipedia

    en.wikipedia.org/wiki/Wave_interference

    The resultant wave may have greater intensity (constructive interference) or lower amplitude (destructive interference) if the two waves are in phase or out of phase, respectively. Interference effects can be observed with all types of waves, for example, light , radio , acoustic , surface water waves , gravity waves , or matter waves as well ...

  5. Crest and trough - Wikipedia

    en.wikipedia.org/wiki/Crest_and_trough

    Crest and trough in a wave. A Crest point on a wave is the highest point of the wave. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave.

  6. Beamforming - Wikipedia

    en.wikipedia.org/wiki/Beamforming

    Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. [1] This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference.

  7. Interferometry - Wikipedia

    en.wikipedia.org/wiki/Interferometry

    Figure 1. The light path through a Michelson interferometer.The two light rays with a common source combine at the half-silvered mirror to reach the detector. They may either interfere constructively (strengthening in intensity) if their light waves arrive in phase, or interfere destructively (weakening in intensity) if they arrive out of phase, depending on the exact distances between the ...
