The shape of the advancing wave front is determined by the envelope of the overlapping spherical wavelets.
A familiar example is a sound wave in air the oscillating motions of the air molecules are induced in the direction of the advancing wave.
"It creates a class of speculative schemers who make it their business to watch the advancing wave of improvement, and gather its foam in the form of patented monopolies, which enable them to lay a heavy tax upon the industry of the country," the court wrote.
The movements of the individual particles of a solid transmitting these waves are normal to the advancing wave front; they vibrate in the direction of propagation of the wave.
Away from the advancing wave of hatred and death that would soon create that great contribution to world shame -- death camps.
Some industry observers, including The Wall Street Journal, have called it the "New Industrial Revolution," touched off by an advancing wave of technology with sensors and microprocessors plummeting in cost and size; cheap and easy cloud storage; and newly nimble forms of communication and software.
The reflected wave travels back towards the heart and meets the advancing wave, augmenting its height.
[1], [3], [23], [24] [26] The reflected wave travels back towards the heart and meets the advancing wave.
[21], [27] As a result, the reflected wave reaches the advancing wave in systole, resulting in significant augmentation of the systolic peak.
When arterial stiffness in increased, the arterial pulse wave travels faster, so the reflected wave reaches advancing wave in the systole, resulting in significant augmentation of the systolic peak.
Second, they indicate that range expansion in Europe occurred by a series of long-distance dispersal events and the establishment of outlying populations, similarly to what was found in e.g. invasive Heracleum taxa in Europe [65] and Centaurea diffusa in North America [64], instead of a simple advancing wave front with stepwise colonisation events.
