Learn what a transverse wave is. Discover the difference between transverse vs. longitudinal waves, examine parts of waves, and study transverse...
plane wavevortex wave beaminterference patternsWe consider relativistic deformations of interfering paraxial waves moving in the transverse direction. Owing to superluminal transverse phase velocities, noticeable deformations of the interference patterns arise w...
(Note: the equation above is based on the physicists' sign convention for wave phasors, rather than the one which is more common in engineering, although in the field of optics one often finds the latter in the scientific literature, where the last phase term is exp(−j[...]). If...
19] have concluded that, although one could add a consistent mass term for the spin-0 sector without problems, there is no mass term in the spin-2 sector that might avoid the presence of ghosts. They have shown that such negative
The polarization state of the beams can be independently adjusted using quarter-wave plates on either side of the trap (see Methods). When the beams have parallel, linear polarization (LP), the only surviving forces in the trap are optical gradient forces. These forces attract the particle ...
See in textbooks the definition of modulated wave. In which sense is wave (7.13) the modulated wave? 2. Sketch separately the plots of the three longitudinal waves from (7.19): first harmonic, second harmonic, and composite wave. Collect together all three waves in one plot and comment on ...
End-diastole was defined as the onset of the R-wave in the ECG. End-systole was determined visually as the moment of end-shortening of the RV free wall. This defi- nition of end-systole was applied because a time delay often exists between pulmonary valve closure and...
The severity of the constriction is usually assessed by measuring pulsed-wave Doppler images of the aortic arch16. However, in this OTAC model, the artifacts of the o-ring make it difficult to assess the signals. The measurement of the peak flow velocity difference between the right and left...
The grating 15 traps acoustic transversal wave on the surface of the substrate 11. Then, a thick screening layer 17 is deposited on the IDTs 12 and 13, the screening layer 17 seals the IDTs to protect them against corrosion, and basically prevents the short-circuiting of the electrodes of...
The apical four-chamber view was used to visualise the mitral valve for indices of diastolic function, including early and late filling velocities (E and A wave), E wave deceleration time, isovolumic relaxation time (IVRT), and total ejection time. The apical four-chamber view was also used...
