London: Edward Arnold & CO. – 1924. – 431 p. There is at present no theory of Optics in the sense that the elastic solid theory was accepted fifty years ago. We have abandoned that theory, and learned that the undulations of light are electromagnetic waves differing only in linear dimensions from the disturbances which are generated by oscillating electric currents or moving magnets. But so long as the character of the displacements which constitute the waves remains undefined we cannot pretend to have established a theory of light. The present volume is divided into two parts; the first part includes those portions of the subject which may be treated without the help of the equations of dynamics, although a short discussion of the kinetics of wave motion is introduced at an early stage. The mathematical treatment has been kept as simple as possible, elementary methods only being used.
