Optics: Ninth Edition Optics: Ninth Edition covers the work necessary for the specialization in such subjects as ophthalmic optics, optical instruments and lens design. The text includes topics such as the propagation and behavior of light; reflection and refraction – their laws and how different media affect them; lenses – thick and thin, cylindrical and subcylindrical; photometry; dispersion and color; interference; and polarization. Also included are topics such as diffraction and holography; the limitation of beams in optical systems and its effects; and lens systems. The book is recommended for engineering students who are in need of an introduction to the subject and the mathematics involved in it.

This revised edition lists approximately 1200 libraries in the UK and the Republic of Ireland, some included for the first time, with details of their rare and special book collections. It covers mainly those printed before 1850, but includes manuscript and modern material where related.

A comprehensive annually-updated guide to higher education offering practical advice on courses and places to study. The book deals with the mechanics of applying to college, and also information on matters from finance and accommodation to a glossary of unfamiliar terms.
