Wave vibrational

Using harmonic overtones, it is possible to sound a tone which will cancel one or more of its octaves reflected in the harmonic scales above and below it. This is easily demonstrated on a cello Suppose a tone, say the open string A, is sounded. The sound is a wave-vibration of air molecules caused by the string, which then acts as a resonator. 

Polar Molecule a molecule where the centers of positive and negative charge differ, creating a permanent dipole moment Polarizability ability of an electron cloud in a neutral atom to be distorted Polarized Light light in which the electromagnetic wave vibrates in only one plane Polyatomic Ion an ion consisting of more than one atom... 

Brighter, tunable ultrafast light sources would benefit many of the areas discussed in the report, particularly infrared-terahertz (between visible light and radio waves) vibrational and dynamical imaging, near-field scanning optical microscopy (NSOM), and X-ray imaging. 

Vision 4 The Wave-Vibration Structure of External Forms... 

If the guide senses that the voyager is experiencing the fragmentation of external sound into wave vibrations, he can amend the instructions appropriately (changing the visuaol references to auditory). 

Those rays, e.g. SO, for which the electric displacement component of the wave vibrates at right angles to the principal section (indicated by the dots) travel at a constant speed irrespective of direction they are the ordinary or o rays. 

The Helmholtz equation resembles the spatial part of the classical wave equation for matter waves (waves in ocean, sound waves, vibrations of a string, electromagnetic waves in vacuum, etc.) of amplitude F = F(r, f) ... 

Birefringence or double refraction This is often the easiest method (Stein and Tobolsky, 1948 De Varies, 1953 and Andrews, 1954). The specific birefringence (An) of a fibre is defined as the difference in refractive index between the two components of a light wave vibrating parallel and perpendicular to the fibre axis (An = n — n, ). Birefringence is made up of contributions from the amorphous and crystalline regions. 

The physical means of defoaming involve foam breakdown by thermal treatment (heating, processing with overheated vapour, freezing), by acoustic (mainly ultrasound) waves, vibrations, a-particles irradiation, creation of high capillary pressure in the foam, etc. 

Unpolarized light consists of waves vibrating in many different planes (indicated by the arrows). The polarizing filter blocks all waves except those vibrating in a given plane. 

The standing-wave vibrational oscillations are most easily detected by coherent scattering of a variably delayed probe pulse phase matched for diffraction with scattering wave vector qo. The oscillations give rise to spatial modulation of the dielectric tensor ... 

Polemized light consists of electromagnetic waves vibrating along one direction ... 

Light can be described as a wave vibrating perpendicular to its direction of propagation. Light vibrating in all possible planes is said to be unpolarized whereas that oscillating in only one plane is plane polarized. 

A prototype of a hyperbolic equation is the wave equation. The wave equation governs many physical phenomena such as the propagation of sound waves, water waves, vibration of a membrane in a two-dimensional setting, and vibration of a string in a one-dimensional setting.
