Excerpt from The Spectroscopy of the Extreme Ultra-Violet
It is to this region that the greater part of this work is dedicated.
In looking back over the foregoing paragraphs, it is at once obvious that the factors which have controlled our knowledge of the ultra-violet end of the spectrum are, first, the absorption of solids; second, the means by which the refracted light was detected; third, the character of the source, and fourth, the absorption of the constituents of the air. By way of intro duction to the Schumann region, therefore, it will be well to pay special attention to the behaviour of these agents in the ultra-violet.
The classic works on spectroscopy require at the outset a detailed account of apparatus, but in the limited scope of the present volume it will be necessary to confine ourselves to those instruments which are not described elsewhere. Thus, as prism and grating spectroscopes are fully treated in many places as far as the ordinary ultra-violet is concerned notably in Kayser's Handbuch and Baly's Spectroscopy, it will not be necessary to mention them until the Schumann region is reached. On the other hand, since instruments for the comparison of the energy given by two sources of light in the ultra-violet are not quite so familiar to the scientific reader, and since the principles involved in them often permit their use in the extreme ultra-violet, we shall begin by some de scription of them.

Paperback. Zustand: New. Print on Demand. The author presents a descriptive journey into the field of extreme ultraviolet spectroscopy. As a specialized field of study, the use of extreme ultraviolet spectroscopy has a relatively short history, with the author tracing its beginnings to the work of Theodore Lyman in the early 1900s. Prior to this, the field of spectroscopy was limited by the absorption of air and available light sources. Lyman's development of a vacuum spectrograph allowed him to go beyond these limitations, opening up new possibilities in the field. The author chronicles the work of others who contributed to the field and provides a detailed look at the various instruments used. This book will appeal to those with a deep interest in the field of science and the history of scientific discovery. The insights gathered from this text could inspire a new generation of scientists to look beyond existing limitations for further advancement in knowledge and understanding of the world around us. 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 9781334260438_0
