  2. Wave interference - Wikipedia

    en.wikipedia.org/wiki/Wave_interference

    Constructive interference occurs when the phase difference between the waves is an even multiple of π (180°), whereas destructive interference occurs when the difference is an odd multiple of π. If the difference between the phases is intermediate between these two extremes, then the magnitude of the displacement of the summed waves lies ...

  3. Fringe shift - Wikipedia

    en.wikipedia.org/wiki/Fringe_shift

    The interaction of the waves on a viewing surface alternates between constructive interference and destructive interference causing alternating lines of dark and light. In the example of a Michelson Interferometer, a single fringe represents one wavelength of the source light and is measured from the center of one bright line to the center of ...

  4. Double-slit experiment - Wikipedia

    en.wikipedia.org/wiki/Double-slit_experiment

    In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior of both classical particles and classical waves.This type of experiment was first performed by Thomas Young in 1801, as a demonstration of the wave behavior of visible light. [1]

  5. Multipath propagation - Wikipedia

    en.wikipedia.org/wiki/Multipath_propagation

    Multipath interference is a phenomenon in the physics of waves whereby a wave from a source travels to a detector via two or more paths and the two (or more) components of the wave interfere constructively or destructively. Multipath interference is a common cause of "ghosting" in analog television broadcasts and of fading of radio waves.

  6. Diffraction - Wikipedia

    en.wikipedia.org/wiki/Diffraction

    Diffraction can occur with any kind of wave. Ocean waves diffract around jetties and other obstacles. Circular waves generated by diffraction from the narrow entrance of a flooded coastal quarry. Sound waves can diffract around objects, which is why one can still hear someone calling even when hiding behind a tree. [26]

  7. Crest and trough - Wikipedia

    en.wikipedia.org/wiki/Crest_and_trough

    A trough is the opposite of a crest, so the minimum or lowest point of the wave. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and

  8. Electron diffraction - Wikipedia

    en.wikipedia.org/wiki/Electron_diffraction

    All matter can be thought of as matter waves, [5]: Chpt 1-3 from small particles such as electrons up to macroscopic objects – although it is impossible to measure any of the "wave-like" behavior of macroscopic objects. Waves can move around objects and create interference patterns, [12]: Chpt 7-8 and a classic example is the Young's two-slit ...

  9. Bragg's law - Wikipedia

    en.wikipedia.org/wiki/Bragg's_law

    Bragg diffraction occurs when radiation of a wavelength λ comparable to atomic spacings is scattered in a specular fashion (mirror-like reflection) by planes of atoms in a crystalline material, and undergoes constructive interference. [10] When the scattered waves are incident at a specific angle, they remain in phase and constructively interfere.
