Dispersive

The samples were also studied with energy-dispersive x-ray spectroscopy.

A generalization to dispersive materials is possible under certain circumstances at the cost of additional terms.

Although these tunable lasers are mainly known in their liquid form, researchers have also demonstrated narrow-linewidth tunable emission in dispersive oscillator configurations incorporating solid-state dye gain media.

An alternate method for acquiring spectra is the "dispersive" or "scanning monochromator " method.

Another is called "Jacquinot's Throughput Advantage": A dispersive measurement requires detecting much lower light levels than an FTIR measurement.

Consequently the powers of the two must be different (in order that be not zero (equation 2)), and the dispersive powers must also be different (according to 4).

During the early 1800s, Joseph von Fraunhofer made experimental advances with dispersive spectrometers that enabled spectroscopy to become a more precise and quantitative scientific technique.

Energy-dispersive X-ray spectroscopy (EDS) performed in 2009 revealed that the inks contained major amounts of iron, sulfur, potassium, calcium and carbon and trace amounts of copper and occasionally zinc.

For an achromatic dispersive lens the converse must be adopted.

For linear non-dispersive materials, though, the general equation leads directly to the simpler energy density equation given above.

For non-dispersive materials this same energy is released when the magnetic field is destroyed so that this energy can be modeled as being stored in the magnetic field.

If a light pulse is propagated through a normally dispersive medium, the result is the higher frequency components slow down more than the lower frequency components.

If its chromatic effect ( ) be greater than that of the same lens, this being made of the more dispersive of the two glasses employed, it is termed hyper-chromatic.

If there is refraction at a collective spherical surface, or through a thin positive lens, O'2 will lie in front of O'1 so long as the angle u2 is greater than u1 (under correction); and conversely with a dispersive surface or lenses (over correction).

In a dispersive medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear.

It determines the focusing power of lenses, the dispersive power of prisms, and generally the path of light through the system.

Newton failed to perceive the existence of media of different dispersive powers required by achromatism; consequently he constructed large reflectors instead of refractors.

Otherwise, both the phase velocity and the group velocity vary with frequency, and the medium is called dispersive ; the relation is known as the dispersion relation of the medium.

Recently, there has been an effort to experimentally image the 1s and 2p orbitials in a SrTiO 3 crystal using scanning transmission electron microscopy with energy dispersive x-ray spectroscopy.

Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium.
