However, it also makes an end blown flute or transverse flute considerably more difficult for a beginner to produce a full sound on than a ducted flute, such as the recorder.

However some high power lasers may be multimode, with the transverse modes often approximated using Hermite-Gaussian or Laguerre-Gaussian functions.

However, longitudinal waves by necessity have only one form for a given propagation direction, rather than two polarizations as in a transverse wave, and thus they were unable to explain the phenomenon of birefringence, where two polarizations of light are refracted differently by a crystal.

However, a century later, Young and Fresnel revived the wave theory of light when they pointed out that light could be a transverse wave rather than a longitudinal wave — the polarization of a transverse wave ( like Newton's " sides " of light ) could explain birefringence, and in the wake of a series of experiments on diffraction the particle model of Newton was finally abandoned.

However, above a certain cutoff frequency, transverse electric ( TE ) or transverse magnetic ( TM ) modes can also propagate, as they do in a waveguide.

However, contrary to the diffusionist theory, it appears that there was simultaneously a structural evolution towards the pointed arch, for the purpose of vaulting spaces of irregular plan, or to bring transverse vaults to the same height as diagonal vaults.

However, waves can exist in plasmas or confined spaces, called plasma waves, which can be longitudinal, transverse, or a mixture of both.

However, this is only true for the spinal cord and the brainstem, since the forebrain end of the neural axis bends crook-like during early morphogenesis into the hypothalamus, where it ends ; the orientation of true transverse sections accordingly changes, and is no longer parallel to the ribs and ground, but perpendicular to them ; lack of awareness of this morphologic brain peculiarity ( present in all vertebrate brains without exceptions ) has caused and still causes erroneous thinking on forebrain brain parts.

However, the Corvair used coil springs at each wheel instead of the Corvette's single transverse leaf spring unit.

However Scott, by his own admission, was no engineer and his design, with reinforced concrete beams ( illustrated ) under the footways, leaving the road to be supported by transverse slabs, was difficult to implement.

However, in the natural world electrons normally remain in an uncertain, non-deterministic, " smeared ", probabilistic wave – particle wavefunction orbital path around ( or through ) the nucleus, defying classical electromagnetism.

However, the wave packet will also spread out as time progresses, which means that the position becomes more uncertain with time.

However, in a triangular dot, the wave functions are mixed due to confinement symmetry.

However, by the late 1960s, many of Structuralism's basic tenets came under attack from a new wave of predominantly French intellectuals such as the philosopher and historian Michel Foucault, the philosopher and social commentator Jacques Derrida, the Marxist philosopher Louis Althusser, and the literary critic Roland Barthes.

However, one of the main scientists associated with the Copenhagen interpretation, Niels Bohr, never had in mind the observer-induced collapse of the wave function, so that Schrödinger's Cat did not pose any riddle to him.

However, at that time, no practical " short wave " ( defined then as any frequency above 500 kHz ) amplifier existed, due to the limitations of existing triodes.

However, if a third medium with a higher refractive index than the low-index second medium is placed within less than several wavelengths distance from the interface between the first medium and the second medium, the evanescent wave will be different from the one under " ordinary conditions " and it will pass energy across the second into the third medium.

" However, by 1874, a new wave of paramilitary organizations arose in the Deep South.

However, a vibration is not necessarily a wave.

However, this notion is problematic for a standing wave ( for example, a wave on a string ), where energy is moving in both directions equally, or for electromagnetic ( e. g., light ) waves in a vacuum, where the concept of medium does not apply and interaction with a target is the key to wave detection and practical applications.

However, at the end of the story, he apparently succumbs to the virus himself before he can escape, his physiology being close enough to that of the Daleks for the virus to affect him.

However, in 1971 Erik Hornung pointed out that the traits of an apparently supreme being could be attributed to many different gods, even in periods when other gods were preeminent, and further argued that references to an unspecified " god " are meant to refer flexibly to any deity.
