Impressive Define Dispersive Power

The power of a transparent medium to separate different colors of light by refraction as measured by the difference in refractivity for two specified widely differing wavelengths divided by the refractivity at some specified intermediate wavelength.

Define dispersive power. In statistics the placement of data points along a chart relative to an average or mean line. Dispersive definition is - of or relating to dispersion. Find the focal length of.

Define dispersive power of a prismWelcome to Doubtnut. Derive an expression for power in terms of voltage and resistance. Doubtnut is Worlds Biggest Platform for Video Solutions of Physics Chemistry Math and Biology Doub.

The dispersive power of the material of a prism is defined as the ratio of angular dispersion between two extreme colours to the deviation produced by the mean colour. The dispersive power of a grating is defined the ratio of the difference in angle of diffraction of any two neighbouring spectral lines to the diffraction in the wavelength between the two spectral lines. Dispersive power of Prism ω.

Dispersion is important to finance as the data points of say a stock determine the mean which in turn helps determines the stocks trendDispersion is also used to determine volatility. Calculate the angular dispersion produced by a prism of angle 6 degree if the refractive indices of material of prism for blue and green colours are 1664 and 1655. Definition of dispersive power.

Asked Nov 13 2017 in Class X Science by aditya23 -2136 points. It is expressed as dθdλ We know ab sinθ nλ Differentiate with respect to λ. The smaller the value of 𝜔 the smaller the range of dispersion that light experiences through the prism.

Dispersion is usually represented by its dispersive power ω or relative dispersion which is equal to the mean dispersion divided by the excess refractive index of the helium d 5876 nm spectral line nd 1 often called the refractivity of the material ω nF nC nd 1. Dispersive power of a medium is defined as the ratio of angular dispersion of white light created by that medium to the mean deviation of light. The dispersive power of the prism can also be expressed in terms of the angle between the two extreme wavelengths.
