NEAR THE HORIZON - AN INVITATION TO GEOMETRIC OPTICS IN SOUTH AFRICA
This item is sold brand new. It is ordered on demand from our supplier and is usually dispatched within 7 - 12 working days Several optical phenomena can occur when the sun is near the horizon, some of which can actually be seen, for instance as a dark strip in the middle of the solar disk, or as a green flash. These are a result of the way the atmosphere affects the geometry of light rays. In this book, Broer uses the Fermat principle to deduce laws for refraction and reflection. By expressing these as conservation laws, he can handle both the case of inhomogeneous layers of air and the case of continuous variation in the refraction index. Building from this elementary theory, more advanced mathematical theories are discussed, including how the Fermat Principle leads to a Riemannian metric whose geodesics are the paths of light rays, thus demonstrating the physical applicability of Riemannian geometry. Intended for teachers and professors to enlighten their courses, or for students and researchers in mathematics, science and engineering. Features Summary Dealing with optical phenomena near the horizon, this book is intended for all levels, including teachers, students and researchers.
