Path Difference and Phase Difference | Lets Learn Nepal
(i.e having a fixed phase relationship) waves. These phase shift is due to different optical paths (either due to the lengths or refractive in- de matière à une particule avec elle-même et une seule particule est présente. In particular, the different angular momentum channels of the scattered conduction electron . mais simples, compréhensibles et même utilisables par des non-spécialistes. .. for the conduction electrons: the wave-functions are phase-shifted. Remarkably, the phase-shift at the Fermi level is related to the occupancy of the. First we write equations for the two waves: [math]y_1=\sin(x+\phi)[/math] interférer deux ondes de même amplitude avec une différence de phase de 3 degrés.
This technique allows non-intrusive flow measurements, at high precision and high frequency. Velocity profile measurement[ edit ] Developed originally for velocity measurements in medical applications blood flowUltrasonic Doppler Velocimetry UDV can measure in real time complete velocity profile in almost any liquids containing particles in suspension such as dust, gas bubbles, emulsions.
Flows can be pulsating, oscillating, laminar or turbulent, stationary or transient. This technique is fully non-invasive. Satellite communication[ edit ] Fast moving satellites can have a Doppler shift of dozens of kilohertz relative to a ground station. The speed, thus magnitude of Doppler effect, changes due to earth curvature. Dynamic Doppler compensation, where the frequency of a signal is changed progressively during transmission, is used so the satellite receives a constant frequency signal.
This results at the listener's ear in rapidly fluctuating frequencies of a keyboard note. Vibration measurement[ edit ] A laser Doppler vibrometer LDV is a non-contact instrument for measuring vibration. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the laser beam frequency due to the motion of the surface.
Developmental biology[ edit ] During the segmentation of vertebrate embryoswaves of gene expression sweep across the presomitic mesodermthe tissue from which the precursors of the vertebrae somites are formed. The vortex into the toroidal photon needs to be dodeca because phase conjugation is how waves sort.
Breathing GAIA:Photosynthesis is Precisely FRACTAL / Phase Conjugation by Golden Ratio
Dan suggests this also explains alphabet origins: The alphabet's symmetry of the vortex index- is a result of the need to phase conjugate- in order to compress and sort and be distributed successfully.
Only that which can phase conjugate can be distributed All the primary and secondary colors are lined up with the dodeca- planes - parallel and perpedicular. The effective color coding angles - are in part also the result of the tilt angles of the tetra into the dodec - may be mostly because getting lined up- or perpendicular with the faces of the dodec is how the light rays acheive the necessary phase conjugation.
Stellating the dodec is natures only 3D way of nesting by Golden Ratio, and Golden Ratio is the only perfect way to phase conjugate - that is - to add AND multiply constructively. Dan suggests that no other principle mechanism could be doing the sorting at the fusion point other than phase conjugation Dan is hypothesizing there is some important parallel to phase conjugation as in a phase conjugate mirror optically; he believes Golden Ratio based phase conjugation IS the primary mechanism by which color is sorted by frequency.
Also Dan believes that this sorting principle for color DOES occur outside of, as well as inside the human perception. Dan suggests this dodeca phase sorting for colors inertial symmetry is also how nature - selectively employs the photon's inertia calibrated in this way - for example in photosynthesis. Human perception of color had to utilize a perception of this phase conjugation phase sorting in order to embed and survive in nature.phase difference and path difference
Dan also believes that the sorting for wavelength which is also a sorting for color bands inside a prism is a 3 dimensional toroidal vortex photon phenomenon. Dan does not believe the sorting by wavelength in a prism can be well described as simply 2D waves.
JMM @ EOST : seismic waves
Description of Regular Pyramid Formations: Phase conjugation by the way light cones sort into Phi ratio constructive interference, by lining up with the implosive approach to a dodecahedron- would thus be consistent to hypothesize as the primary mechanism by which color is sorted into wavelength.
Enabling a fusion point and therefore the sorting in to color - would seem to be clearly the result of the infinite golden ratio vertex x,y,z values of the infinite stellated dodecahedron constructive heterodyning. IF the dodec itself predicts color segregation by frequency- this could be powerful evidence that the dodeca symmetry itself is key to optical sorting and fusion by phase conjugation.
