Adjective:

तितर-बितर करनेवाला, इधर-उधर करनेवाला, अलग-थलग करनेवाला, फैलानेवाला,

dispersive's Usage Examples:

If we denote its deviation by S D, then we may put Dispersive power = (F - Sc)/S D.

If the refracting angleof the prism is small, then the ratio of the dispersion to the mean deviation of the two rays is the dispersive power of the material of the prism.

All material media, however, ' are more or less dispersive.

The phenomenon of dispersion shows that in dispersive media the velocity is different for lights of different wave-lengths.

The spectrum will be straight if the twoprismsaresimilar in dispersive property, but if one of them is con structed of a material which possesses any peculiarity in this respect it will be revealed by the curvature of the spectrum.

The symbol v represents the inverse of the dispersive power, its value being (nD-i)/(C-F).

- The optical desideratum is uniformity of refractive index and dispersive power throughout the mass of the glass.

By altering the distance of the collective and dispersive members the magnification can be widely varied.

The dispersive powers of gases are, however, generally comparable with those of liquids and solids.

On the other hand, while in the older crown and flint glasses the relation between refraction and dispersion had been practically fixed, dispersion and refraction increasing regularly with the density of the glass, in some of the new glasses introduced by Abbe and Schott this relation is altered and a relatively low refractive index is accompanied by a relatively high dispersion, while in others a high refractive index is associated with low dispersive power.
