The book was written because the subject, 'which, at the university, proves to be full of lively interest, is too often at school a dreary grind of thinly disguised geometry' and 'much of value is lost in this way'. Offering a vibrant account of electromagnetic theory of radiation and an 'explanation of nearly all the phenomena hitherto investigated', this book presents 'an alternative approach to the subject'. Chapters are detailed and broad in scope; chapter titles include, 'The behaviour of light', 'The velocity of light' and 'Sources of light'. Notably, the wave concept is used as the means of approach and multiple examples are included at the back for reference. This book will be of significant value to anyone with an interest in optics and the history of education.Preface; 1. Historical; 2. Waves and wave-motion; 3. The behaviour of ripples; 4.
