Publications of the Astronomical Society of the Pacific, Vol. 115, No. 804 (February 2003), pp. 235-242 (8 pages) ABSTRACT We present a design for a zero‐deviation cross‐disperser to be used with ...

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 ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Robert Kelly is managing director of XTS ...

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 ...

Explore the multifaceted concept of the prism, illustrating how it reflects the interplay between perception, light, and ...

Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...

A thin beam of white light from an overhead projector goes into a prism, dispersing the colours into a rainbow. Turn on the projector. Hold the prism by the parallel flat faces, with one of the points ...
