In contrast, when the valley of one light wave overlaps with the peak of another light wave, the two
waves cancel each other out (destructive interference).
A ceiling - mounted microphone detects low - frequency noise and the system then generates out - of - phase frequencies — the sound
waves cancel each other out.
Not exact matches
When the gravitational waters of spacetime are calm, the beams recombine at the junction and
cancel each
other out — the troughs of one beam's 1,064 - nanometer
waves of laser light completely negate the crests of the second beam's
waves.
The distance between the fibers affects how light
waves interfere with each
other to
cancel out some wavelengths of light and not
others, thus affecting what colors you perceive.
If the polarization of the two counter-propagating light
waves is transverse, they will enhance each
other at certain locations while
cancelling out in
other places.
By setting the phase differences just right, the researchers make the
waves combine to reinforce one another in some places and
cancel out one another in
other places.
The silicon modulator splits laser beams into two channels, where the light
waves can be manipulated to either
cancel each
other out (0) or travel side by side (1) when recombined.
Scattered light signals arriving over different paths will actually
cancel each
other out: The troughs of one
wave will align with the crests of another.
«That trapped light builds up in intensity until it almost exactly
cancels the incoming light,» in the same way that two colliding sound
waves can zero each
other out.
In
other places the
waves cancel themselves
out, leading to the dark spaces you see between the spots.
Instead of aiming its mirrors straight at a planet and then combining the light
waves, TPF will aim its mirrors at the host star and then let the light
waves from the different mirrors
cancel each
other out by combining the peaks of one mirror's
waves with the troughs of another's.
The individual
waves were still oscillating quickly but they were oscillating at the same frequency in opposite directions, meaning at certain points they
canceled each
other out and
other points they added together, creating an all light or all dark pattern.
Not to worry, Kakalios says: in the same way that sound
waves can be
canceled by running
other waves out of synch with them, one could destroy intrinsic fields by
canceling them
out with
others.
The ESA plans to build FEEP into the LISA Pathfinder, a spacecraft designed to detect gravitational
waves while stationed at Lagrange point L1, where the gravitational fields of Earth and the sun
cancel each
other out.
If one
wave is at its peak, the
other at its lowest point, the two
cancel one another
out, and there is no current,» explains Prof. Dr. Peter Hommelhoff from the Chair of Laser Physics.
The
waves alternately
cancel out and amplify each
other so that the sea surface goes from wavy to flat to wavy.
They contributed to the work of
canceling out the
other myriad noises picked up by the twin LIGO detectors in Hanford, Wash., and Livingston, La., that weren't gravitational
waves.
Without any spacetime ripples, the laser light
waves from the two arms will perfectly
cancel each
other out, so nothing will reach a photodetector.
Solar activity will fall by 60 per cent as two
waves of fluid «effectively
cancel each
other out», according to Prof Valentina Zharkova.
At each point, a series of concentric
waves is generated, but most ot those
cancel each
other out.
