Light and Electricity: Notes of Two Courses of Lectures Before the Royal Institution of Great Britain

Light And Electricity: Notes Of Two Courses Of Lectures Before The Royal Institution Of Great Britain by John Tyndall. This volume presents notes prepared for the Royal Institution lectures, combining and republishing the American edition in a single, accessible work. It surveys the physics of light and the fundamentals of electricity, from rectilinear propagation and shadows to the inverse-square law, photometry, brightness, and the nature of light. It explains the formation of images, plane and curved mirrors, refraction, total internal reflection, lenses, vision and the eye, and the phenomena of interference, diffraction, and the spectrum, including Fraunhofer’s lines, color, fluorescence, and radiation. The electricity portion covers voltaic cells, electro-magnetism, induction, electric machines, and the discharge of gases, with classic experiments by Faraday, Fizeau, Foucault, Wheatstone, Siemens, and others. The work blends rigorous explanation with vivid experimental illustration, intended for instructors and learners seeking a solid foundation in light and electricity. Originally published in 1871.
