As a basis for understanding fluorescence, color and wavelength are discussed as well as the relationship of visible light with other radiations. A number of colorful experiments are outlined illustrating the principles involved. Additional experiments demonstrate some of the practical applications of ultraviolet and fluorescence. This thin little handbook is in good condition, with little wear. Pages are clean and unmarked. Saddle stitching shows no wear. There is a little scuff in the upper right corner of the front cover. 64 pages, printed in 1965.
