  2. 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 ...

  3. Rusty bolt effect - Wikipedia

    en.wikipedia.org/wiki/Rusty_bolt_effect

    The rusty bolt effect is a form of radio interference due to interactions of the radio waves with dirty connections or corroded parts. [1] It is more properly known as passive intermodulation , [ 1 ] and can result from a variety of different causes such as ferromagnetic conduction metals, [ 2 ] or nonlinear microwave absorbers and loads. [ 3 ]

  4. Double-slit experiment - Wikipedia

    en.wikipedia.org/wiki/Double-slit_experiment

    The interference pattern between the two electron waves could then be observed. [67] In 2017, researchers performed the double-slit experiment using light-induced field electron emitters. With this technique, emission sites can be optically selected on a scale of ten nanometers.

  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. Electromagnetic interference - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_interference

    Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. [1]

  7. Coherence (physics) - Wikipedia

    en.wikipedia.org/wiki/Coherence_(physics)

    Each slit acts as a separate but in-phase beam contributing to the intensity pattern on a screen. These two contributions give rise to an intensity pattern of bright bands due to constructive interference, interlaced with dark bands due to destructive interference, on a downstream screen. Many variations of this experiment have been demonstrated.

  9. Phase-contrast microscopy - Wikipedia

    en.wikipedia.org/wiki/Phase-contrast_microscopy

    Differential interference contrast microscopy, Hoffman modulation-contrast microscopy, Quantitative phase-contrast microscopy Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image.
