A propos du livre

Présentation de l'éditeur

In connection with my work on the coronas as a means for the study of nucleation, I came across a principle of interferometry which seemed of sufficient importance to justify special investigation. This has been undertaken in the following chapters, and what appears to be a new procedure in interferometry of great promise and varied application has been developed. In case of the coronas there is a marked interference phenomenon superposed on the diffractions. The present method is therefore to consist in a simplification or systematization of this effect, by bringing two complete component diffraction spectra, from the same source of light, to interfere. This may be done in many ways, either directly, or with a halved transmission or reflecting grating, or by using modifications of the devices of Jamin, Michelson, and others for separating the components. In the direct method, chapters II and III, a mirror immediately behind the grating returns the reflected-diffracted and diffracted-reflected rays, to be superimposed for interference, producing a series of phenomena which are eminently useful, in addition to their great beauty. In fact the interferometer so constructed needs but ordinary plate glass and replica gratings. It gives equidistant fringes, rigorously straight, and their distance apart and inclination are thus measurable by ocular micrometry. The fringes are duplex in character and an adjustment may be made whereby ten small fringes occupy the same space in the field as one large fringe, so that sudden expansions within the limits of the large fringe (as for instance in magnetostriction) are determinable. This has not been feasible heretofore. Length and small angles (seconds of arc) are thus subject to micrometric measurement. Finally the interferences are very easily produced and are strong with white light, while the spectrum line may be kept i

Présentation de l'éditeur

Leopold Classic Library is delighted to publish this classic book as part of our extensive collection. As part of our on-going commitment to delivering value to the reader, we have also provided you with a link to a website, where you may download a digital version of this work for free. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. Whilst the books in this collection have not been hand curated, an aim of our publishing program is to facilitate rapid access to this vast reservoir of literature. As a result of this book being first published many decades ago, it may have occasional imperfections. These imperfections may include poor picture quality, blurred or missing text. While some of these imperfections may have appeared in the original work, others may have resulted from the scanning process that has been applied. However, our view is that this is a significant literary work, which deserves to be brought back into print after many decades. While some publishers have applied optical character recognition (OCR), this approach has its own drawbacks, which include formatting errors, misspelt words, or the presence of inappropriate characters. Our philosophy has been guided by a desire to provide the reader with an experience that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic book, and that the occasional imperfection that it might contain will not detract from the experience.
