The transmission of the arterial pressure pulse does not give the true PWV as it is a sum of vectors of the incident and reflected waves.
42.
But there is still the possibility that " a funny arrangement of rocks and other things " could be responsible for the reflected waves recorded by Clementine.
43.
Modern seawalls aim to re-direct most of the incident energy, resulting in low reflected waves and much reduced turbulence and thus take the form of sloping revetments.
44.
When the wave reaches the end of the line, in general, there will be a reflected wave which travels back along the line in the opposite direction.
45.
Appleton found in fact that it increased as the sun set and then decreased as the sun rose until the reflected wave was too weak to record.
46.
Where the \ scriptstyle a _ k are the incident waves and the \ scriptstyle b _ k are the reflected waves at port " k ".
47.
The speed of propagation ( i . e . PWV ) is increased in stiffer arteries and consequently reflected waves will arrive at the heart earlier in systole.
48.
Beyond the horizon the direct and reflected waves are blocked by the curvature of the Earth, and the signal is purely made up of the diffracted surface wave.
49.
The reflected wave from the top of the film and the reflected wave from the film / material interface are then exactly 180?out of phase, causing destructive interference.
