Excerpt from On Radiation
By means of a prism Sir Isaac Newton unravelled the texture of solar light, and by the same simple instrument we can investigate the luminous changes of our platinum wire. In passing through the prism all its rays (and they are infinite in variety) are bent or refracted from their straight course; and as dif ferent rays are differently refracted by the prism, we are by it enabled to separate one class of rays from another. By such prismatic analysis Dr Draper has shown, that when the platinum wire first begins to glow, the light emitted is a pure red. As the glow augments the red becomes more brilliant, but at the same time orange rays are added to the em1ss1on. Augmenting the temperature still further, yellow rays appear beside the orange, after the yellow green rays are emitted, and after the green come, in succession, blue, indigo and violet rays. To display all these colours at the same time the platinum wire must be white-hotmthe impression of whiteness being in fact produced by the simultaneous action of all these colours on the optic nerve.

Paperback. Condizione: New. Print on Demand. This book examines the nature of radiation, encompassing both light that we can see and the invisible rays beyond our visual spectrum. Building on groundbreaking work by Sir William Herschel and others, the author presents a comprehensive analysis of radiation and its properties, drawing from experiments conducted using innovative instruments, including the thermoelectric pile. The book delves into the fascinating world of atomic physics, exploring how the structure of various atoms influences their interactions with radiant heat, and discusses the significance of chemical combinations in altering the behavior of molecules when exposed to radiation. A particular focus is given to the role of aqueous vapor in regulating terrestrial temperatures, highlighting its impact on climate and the delicate balance of our planet's ecosystem. Through its in-depth exploration of this fundamental aspect of physics, this book provides a valuable resource for students, researchers, and anyone seeking a deeper understanding of the intricate interplay between matter and energy.
