Definitions

n.名词 noun
  1. 1

    Physics.

    • : the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands at the edge of a shadow.
    • : the bending of waves, especially sound and light waves, around obstacles in their path.

  • The diffraction pattern of the X-rays allows researchers to build up a picture of the internal structure of the protein.

  • The phenomenon is purely optical, involving diffraction of light.

  • It is therefore certain that this is a phenomenon of the diffraction of light simply produced by the vesicles of the mist.

  • X-ray-diffraction studies showed no material differences, nor were there detectable differences in “feel”, smell, or plasticity.

  • Perfect transparency is obtained since there is neither refraction nor diffraction of the visible colors.

  • This diffraction of light first proved to us definitely the reality of the undulatory theory of light.
