They also have a good idea why the Doppler effect occurs. And they've incorporated its principles into a variety of useful tools and gadgets. In this article, we'll examine everything Doppler: the man, the science and the technologies. But first we have to lay some groundwork. Because ...
Another example occurs when cars race around a racetrack. You can hear a definite shift in the sound of the car as it passes where you are standing. One last example is the change in tone you hear when a police car passes you with its siren on. I'm sure that at some point in our...
The parametric Doppler effect that occurs upon reflection of a plane monochromatic wave obliquely incident on an inhomogeneity of the refractive index moving in a medium with a frequency dispersion (homogeneous wave regimes) is analyzed. For a plasma-type frequency dispersion, the dependences of the ...
The frequency conversion under the parametric Doppler effect, which occurs when weak probe radiation reflects off from a refractive index inhomogeneity induced in a nonlinear medium by intense pumping, has been analyzed. Under these conditions, the frequency dispersion of the medium is assumed to ...
In theSoundWave paperthey talk about a phenomenon that occurs when you move your hand too quickly. (See Figure 2d.) A new bulge is formed. I didn't implement the method they described for reducing this, but it should be pretty easy. What I'm doing at the moment to calculate the bandw...
The resonant Faraday effect occurs for radiation at frequencies close to the absorption lines of a magneto-active material. In the paper we present a theory for isolated absorption lines with Voigt profiles. The background source is also assumed to have a Voigt profile. The theory shows how ...
c. To remove or unwind (thread, for example), as from a spool: wound the line off the reel. 7. To lift or haul by means of a windlass or winch: Wind the pail to the top of the well. v.intr. 1. To move in or have a curving or twisting course: a river winding through a ...
The initial antiplatelet effect occurs within 30 min, reaching the peak effect at approximately 2 h [193]. The mean plasma half-life of ticagrelor is 8 h, with elimination primarily via the gastrointestinal system [194]. Although activation is not required for the platelet inhibitory effect of ...
Afterwards, we investigate the implications of the relativistic Doppler effect for the quantum state transformations of wave packets of light and show that a local photon is a local photon at the same point in the spacetime diagram in all inertial frames. Keywords: quantum electrodynamics; special ...
Chronic heart failure (CHF) is a complex syndrome that occurs as a result of structural and functional disorders affecting the ability of the heart to supply oxygen to tissue. Heart failure is the leading cause of morbidity and mortality and causes high health-related costs [1]. Despite the ...
