How to use diffraction pattern in a sentence
If the aperture and wave-length increase in the same proportion, the size and shape of the diffraction pattern undergo no change.
The diffraction pattern is therefore that due to a single aperture, merely brightened n times.
By this procedure the width of the central band in the diffraction pattern is halved, and so far an advantage is attained.
Scientific definitions for diffraction pattern
The interference pattern that results when a wave or a series of waves undergoes diffraction, as when passed through a diffraction grating or the lattices of a crystal. The pattern provides information about the frequency of the wave and the structure of the material causing the diffraction. See also interferometer.
