Excerpt from Miscellaneous Papers Connected With Physical Science It is well known that when a ray of light is incident upon certain crystals, such as Iceland spar and quartz, it is in general divided into two pencils, of which one is refracted according to the known law of the sines, while the direction of the other is determined by a new and extraordinary law, first assigned by Huygens. These laws were long supposed to apply to all doubly-refracting substances; and it was not until the subject was examined by the ablest advocate of the undulatory theory, that the problem of double refraction was solved in all its generality. Setting out from the hypothesis, that the elasticity of the vibrating medium within the crystal is unequal in three rectangular directions, Fresnel has shown that the surface of the wave is not, in general, either a sphere or spheroid, as in the Huygenian law, but a surface of the fourth order, consisting of two sheets; and that the directions of the two refracted rays are determined by tangent planes drawn to these surfaces under known conditions. Such crystals have, in general, two optic axes, and are thence denominated biaxal. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Paperback. Condition: New. Print on Demand. This book explores the nature of light and its physical properties, with a specific focus on the wave theory of light. It discusses the various phenomena associated with light, including propagation, refraction, diffraction, and the colors of thin and thick plates. The author presents both the strengths and weaknesses of the wave theory, contrasting it with the theory of emission. The book explores the implications of the wave theory for our understanding of light and its behavior, providing a comprehensive overview of this important physical theory.
