Geometrical optics

This book consists of nine chapters, which deals with transmission of light on reflection of light, refraction of light, a reflected image plane, a refracted image plane, prism reflection of light and refraction of light in a sphere, thin lens, thick lens like principal point, nodal point and magnifying glass, stop and its action such as types of aperture, field stop and aperture stop aberration like spherical aberration, coma aberration and application of aberration, ray tracing like y-nu ray tracing and an exact ray tracing. Answers and explanation for the questions are in the end of this book.
