Excerpt from Light for Students This book has been written to meet the requirements of students who wish to obtain an accurate and comprehensive knowledge of Geometrical and Physical Optics. In many instances results of recent researches are described, in connection with important laws which they elucidate. The mathematical investigations have, in all cases, been rendered as simple as possible, and have been developed so as to direct attention to the physical aspect of the subject. No knowledge of the Calculus is assumed on the part of the student. A number of illustrative experiments which may readily be performed are fully described, and numerous questions, mostly selected from public examination papers, are appended. The first ten chapters are devoted to Geometrical Optics, i.e., to explaining the consequences of the laws of Reflection and Refraction of Light. Some of the most important optical instruments, including the eye, are dealt with. Points which commonly present difficulties to students, such, for example, as the method of achromatising an eye-piece, are explained in considerable detail. The remaining ten chapters are devoted to the development of the Wave Theory of Light. While ample attention is devoted to the more elementary parts of the subject, full explanations are also given of many points not usually dealt with in books of similar scope; as instances, the investigation of the velocity of transverse waves in an elastic solid, and Sellmeier's Theory of Dispersion, may be mentioned.
