Excerpt from Spectral Photometric Studies
The question which we are then called upon to solve is, does the doubling of the amount of light in this manner double the intensity of every part of the spectrum?
Let us imagine, first, an infinitely narrow slit; the spectrum from such a source may be called a pure spectrum, since any point in it will contain light of but one wave-length. If this slit be moved in a direction perpendicular to the edge of the prism the spectrum will travel in the same direction; and a stationary point, as the light traveled over it, would be illuminated by light of different colors. Next, let us consider a wide slit, and think of its being divided into infinitely narrow ones; we recognize that every part of the spectrum from such a source will consist of lights of different wave-lengths superposed upon each other. Such a spectrum we will call an impure one, and it is with such that we are required to deal in practical measurements.

Paperback. Zustand: New. Print on Demand. This book delves into the relationship between the width of a spectrometer's collimator slit and the intensity of the resulting spectrum. The author, a prominent astrophysicist, investigates the validity of Vierordt's method, which assumes a direct proportionality between these factors. Through meticulous experimentation, the author reveals the limitations of this assumption, demonstrating that deviations occur, particularly at the spectrum's extremes. The author's findings have significant implications for the field of spectroscopy, providing a more nuanced understanding of the factors that influence spectral intensity measurements. The book contributes to the ongoing refinement of spectroscopic techniques, ensuring greater accuracy and reliability in scientific research and applications. Its insights will be invaluable to spectroscopists, astronomers, and anyone seeking a deeper understanding of the principles underlying this crucial analytical tool. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9781334259807_0
