(optics)
The interaction of superimposed light from two different sources when the phase relationship is such as to reduce or cancel the resultant intensity to less than the sum of the individual lights.

The symptoms of destructive interference are clearly shown, whereby the sunflower oil color is brighter while the moisture color appears darker.
The main effect of the eigenbound state is current reduction when there is a destructive interference inside the well (the Sisyphus effect).
The effect of destructive interference between the direct and the reflected sound waves at the microphone is not considered in this work because the unvested frequencies are considered destroyed.
Unruh in [6, 7] clearly has accepted the existence of unmeasured destructive interference at path 5 (pure state density matrix) plus a direct which way claim stating that |[[psi].sub.1] and |[psi].sub.2] are respectively eigenstates of the detectors [D.sub.1] and [D.sub.2], thus it is easy for one to show that Unruh's analysis is mathematically inconsistent [2].
When light passes through an array of thin parallel obstructions, its waves diffract around them and the resulting constructive and destructive interference spatially separates the wavelengths.
Rather than a stationary fringe pattern, which constructive and destructive interference produces in an interference microscope, the pattern in a Doppler vibrometer is moving at a rate proportional to the MEMS device motion.
It is the destructive interference of the frequency moving through the material with the electronic corona beam that is digitally compared to the calibration standard for valuation.
In physics, this phenomenon is called "destructive interference." The premise assumes that everything has a frequency to it.
This layering technique, which generates simultaneously constructive and destructive interference patterns, is a constant motif for Panter.
In the branching measurements, it seems, waves bouncing back to the channel were interfering with other waves, creating patterns of crests and troughs from constructive and destructive interference.
Instead, the optical pattern in the far-field is characterized by the diffraction orders that result from the constructive and destructive interference of all of the light waves that emerge, each from a different aperture of the grating.
The relative amplitudes of, and constructive and destructive interference effects among the signals radiated by the individual antennas determine the radiation pattern of the array.
