Does anyone else notice? That we only get covid numbers from countries that are members of the UN? No coincidence! 🙏❤️🇺🇸🙅

Or Countries with 5G?

I agree. other than China and 5G. Which has always perplexed me. How we havent heard a peep about their COVI numbers since it's release!. Goes to show just how much influence they have over our fake propaganda news outlets? SMH

Wave interference is a phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.

In a transverse wave, particles of the medium vibrate up and down perpendicular to the direction of the wave. In a longitudinal wave, particles of the medium vibrate back and forth parallel to the direction of the wave.

Scanning in transverse planes means that the ultrasound beam is entering the body from either an anterior, posterior, or lateral direction and that the anatomic portion of body structures being visualized from that particular direction are: • Beam entering from an anterior or posterior direction: • Anterior.

A transverse mode of electromagnetic radiation is a particular electromagnetic field pattern of the radiation in the plane perpendicular (i.e., transverse) to the radiation's propagation direction. Transverse modes occur in radio waves and microwaves confined to a waveguide, and also in light waves in an optical fiber and in a laser's optical resonator.

Transverse modes occur because of boundary conditions imposed on the wave by the waveguide. For example, a radio wave in a hollow metal waveguide must have zero tangential electric field amplitude at the walls of the waveguide, so the transverse pattern of the electric field of waves is restricted to those that fit between the walls. For this reason, the modes supported by a waveguide are quantized. The allowed modes can be found by solving Maxwell's equations for the boundary conditions of a given waveguide.

An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators and some interferometers. Light confined in the cavity reflects multiple times, producing standing waves for certain resonance frequencies. The standing wave patterns produced are called modes; longitudinal modes differ only in frequency while transverse modes differ for different frequencies and have different intensity patterns across the cross-section of the beam.

Different resonator types are distinguished by the focal lengths of the two mirrors and the distance between them. Flat mirrors are not often used because of the difficulty of aligning them to the needed precision. The geometry (resonator type) must be chosen so that the beam remains stable, i.e. the size of the beam does not continually grow with multiple reflections. Resonator types are also designed to meet other criteria such as minimum beam waist or having no focal point (and therefore intense light at that point) inside the cavity.

Optical cavities are designed to have a large Q factor; a beam will reflect a very large number of times with little attenuation. Therefore, the frequency line width of the beam is very small indeed compared to the frequency of the laser.

(transitive, medicine) To reduce the virulence of a bacterium or virus.

(transitive, electronics) To reduce the amplitude of an electrical, radio, or optical signal.

attenuate (third-person singular simple present attenuates, present participle attenuating, simple past and past participle attenuated)

Attenuation in ultrasound is the reduction in amplitude of the ultrasound beam as a function of distance through the imaging medium. Accounting for attenuation effects in ultrasound is important because a reduced signal amplitude can affect the quality of the image produced.

Sonocrystallization involves the application of ultrasound energy to control the nucleation and crystal growth of a crystallization process.

Optical tweezers can be used to manipulate droplets, vesicles and vesicle membranes, as shown in the example of a sucrose-filled giant unilamellar vesicle (GUV) in Fig. 18.1. In fact, just like with solid particles, it is possible to transport and release droplets and vesicles. Differently from solid particles, though, droplets and vesicles can be brought together and made to coalesce into larger droplets and vesicles in a process where their contents get mixed.

By doing so, it is possible to use droplets and vesicles as movable reaction vessels containing tiny amounts of desired reagents for combinatorial chemistry studies using ultrasmall (in the femtolitre range) volumes. These mechanical manipulations can then be coupled to spectroscopic probing techniques in order to measure and understand mixing and coalescence processes as they happen, in real time. In this Chapter, we will review progress in experiments regarding the fusion of droplets and vesicles, the spectro- scopic study of the resulting chemical mixing processes and also the action of optical trapping on the encapsulating vesicle membrane itself.

so basically 5G is microwaving people alive since we're made of mostly H2O and destroying our cells in the process depending on the tuning of the waves pattern. is that right?

In a plasma, some electrons have been stripped away from their atoms. ... An ionized atom can be missing a few electrons (or even just one), or it can be stripped of electrons entirely leaving behind an atomic nucleus (of one or more protons and usually some neutrons). Atoms that are missing electrons are called "ions".

late Middle English (in the sense ‘the action of appearing’): from Latin apparitio(n- ) ‘attendance’, from the verb apparere (see appear).

apparition (plural apparitions)

An act of becoming visible; appearance; visibility.

mid-14c., from Old French visable, visible "perceptible" (12c.) and directly from Latin visibilis "that may be seen," from visus, past participle of videre "to see" (see vision). An Old English word for this was. Related: Visibly.

Quantum dot developer QD Vision has received a new round of investment led by Tsing Capital and BASF Venture Capital totaling approximately $22 million from both existing investors and new investors. The funds will be used to advance R&D efforts and support commercialization of new products.

Quantum dots are semiconductor materials. When designed for displays, they accept blue LED light and re-emit in the green or red range. The size of the quantum dot determines the peak wavelengths and the distribution of sizes determines the Full Width Half Maximum (FWHM or the 'peakiness' of the output).

mid 16th century: probably a back-formation from peaked, variant of dialect picked ‘pointed’.

Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. ... Wavelength is inversely related to frequency, which refers to the number of wave cycles per second. The higher the frequency of the signal, the shorter the wavelength.

Piezoelectricity is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat.

When a localized disturbance is applied suddenly into a medium, it will propagate to other parts of this medium.

The local excitation is not detected at other positions of the medium instantaneously, as some time would be necessary for the disturbance to propagate from its source to other parts of the medium. This simple fact constitutes a general basis for the interesting subject of “wave propagation.” Well-cited examples of wave propagation in different media include, for instance, the transmission of sound in air, the propagation of a seismic disturbance in the earth, the transmission of radio waves, among others. In the particular case, when the suddenly applied disturbance is mechanical, e.g., an impact force, the resulting waves in the medium are due to mechanical stress effects and, thus, these waves are referred to as “mechanical stress waves” or simply “stress waves.” Our attention in this text is restricted to the study of the propagation of stress waves in engineering materials.
