Prisms are commonly used in spectroscopy for dispersing or controlling the direction or polarisation of light. This can be helpful for splitting the incoming light into its wavelength components to ...

IN studying the spectra of coloured solutions and solid substances by means of the spectrum microscope, it is most important to employ prisms having a suitable amount of dispersion. It would be a very ...

COMPOUND PRISM OF UNIFORM DISPERSION.—Messrs. C. G. Abbot and F. E. Fowle, of the Astrophysical Observatory at the Smithsonian Institution, have been investigating the possibility of obtaining a ...

Dispersion is an important statistical measure that quantifies the range of outcomes among the components of an index during a specific period. The S&P 500 Realized Dispersion Indices offer two ...

The total quantity of metal available for the reaction needs to be measured to characterize a catalyst sample. The available metal is measured in terms of a percentage of the total number of surface ...
