  • Outside the academic team's multimillion-dollar practice facility, she could hear the incoherent voices of the football players as they again tried to drum up support for an after-school team.
  • incoherent light
  • incoherent beam
  • incoherent feedforward

And so you have an incoherent light source.

Examples

  • Examples of incoherent light sources, like some LEDs, emit waves that lack definite phase connections.

  • The first experiment employed a quasi-monochromatic light beam that was partially spatially incoherent.

  • And so you have an incoherent light source.

  • Because you start to be able to control the flow of energy and take it from an incoherent state, which has little power.

  • The light is incoherent, the phases, therefore the colours have no phase relationship.

  • What we hear as incoherent noise may actually be a musical masterpiece.

  • Such applications could use self-trapped beams from incoherent sources such as light-emitting diodes.

    Academic text (1998)
  • The dashed curve indicates the detected flux for high-frequency, incoherent waves—that is, phonons.

    Academic text (1995)
  • Another experiment demonstrated self-trapping of dark incoherent "beams"—that is, one- or two-dimensional voids nested in a spatially incoherent beam.

    Academic text (1998)
  • The study of incoherent waves revealed that they do not have a stable phase relationship.

Morphology

incoherent = coherent (semi-transparent) = in + coherent

The negation is clear but the physics sense is technical; learners may not know the scientific meaning of 'coherent'.

Etymology

Incoherent comes from the parts in- 'not' and cohere 'to stick together', so in physics it means waves that do not 'stick together' or line up, and therefore do not make a clear combined pattern.
