| Text PROPERTIES OF LIGHT
1. Light and its various phenomena present some of the most interesting studies in the whole realm of physics. They are interesting because the results of many experiments are revealed through the sense of vision as color phenomena. Equally important and every bit as interesting is the historical development and discovery of the various principles, concepts, and properties of light which give rise to these phenomena. All of the various known properties 'of light are conveniently described in terms of the. experiments by which they were discovered and the many and varied experiments by which they are now continually demonstrated. Numerous as they are, these experiments may be grouped together and classified under one of the three following heads: 1) geometrical optics, 2) physical optics, and 3) quantum optics. Each of these may be subdivided as follows: geometrical optics: rectilinear propagation, finite velocity, reflection, refraction; physical optics: diffraction, interference, polarization double refraction; quantum optics: photoelectric effect, Comp-ton effect, atomic excitation, pair production. жүктеу/скачать 1,54 Mb.
