Excerpt from Notes on Standard Wave Lengths Spectrographs, and Spectrum Tubes
The weight assigned to each value is based up0n the mumbe1 of observations with relatively large orders 0f interference and is therefore indicative of the probable relative accuracy. From the concordance among difierent sets of observations on the well determined lines it appears that the probable errors in these are less than 0. 001 A, although our value £01 4799 exceeds Michelson's by 0. 005 A.

Paperback. Zustand: New. Print on Demand. This book offers a comprehensive collection of notes and technical descriptions on the use of wave lengths, spectrographs, and spectrum tubes. It begins with notes on the standard wave lengths of cadmium, discussing several secondary wave-length standards and frequency differences between corresponding pairs of lines in subordinate series to test their accuracy. It also delves into the design of a âquartz rock salt spectrographâ developed for photographing interference phenomena in the ultraviolet spectrum, and describes the characteristics of a concave grating mounting that generates stigmatic spectral images. An additional topic covered by this book is the process of preparing spectrum tubes commonly used in optical demonstrations, testing, and research, providing instructions and suggestions for filling tubes with various gases such as hydrogen, nitrogen, oxygen, helium, neon, and argon. The author includes helpful information on obtaining pure gas spectra by removing common contaminants and ensuring proper electrode selection for each gas. 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 9781334261459_0
