Query: Wonderful

As an introductory book teaching classical (and some modern) optics, this wonderful book is difficult to beat.It prepares you remarkably well for any direction in optics you then want to set off in. The explanations are mostly crystal-clear, crafted with great care. Lots of words and diagrams, not too much math, but enough math to facilitate useful calculations.An excellent under-graduate text, to my mind, the best available today.
