Page 257 - In a word, the Elements of Physics is a book which has been written for use in such institutions as give their undergraduates a reasonably good mathematical training. It is intended for teachers who desire to treat their subject as an exact science, and who are prepared to supplement the brief subject-matter of the text by demonstration, illustration, and discussion drawn from the fund of their own knowledge. THE MACMILLAN COMPANY 66 FIFTH AVENUE, NEW YORK CHICAGO BOSTON SAN FRANCISCO ATLANTA OF...

Page 83 - by passage through the prism P. This fan-like beam falling upon a screen 55 produces an illuminated band RV, called a spectrum, which is red at the end R and passes by insensible gradations through orange, yellow, green, and blue to violet at the end V. The beam B of white light is said to be dispersed by the prism. A photographic plate reveals the existence of invisible rays beyond V. These rays are called ultra-violet rays. The brilliant light of the sun and of the electric arc are especially...

Page 258 - The work as a whole cannot be too highly commended. Its brief outlines of the various experiments are very satisfactory, its descriptions of apparatus are excellent ; its numerous suggestions are calculated to develop the thinking and reasoning powers of the student. The diagrams are carefully prepared, and its frequent citations of original sources of information are of the greatest value.

Page 257 - ... stating these principles, free use has been made of the calculus, but no demand has been made upon the student beyond that supplied by the ordinary elementary college courses on this subject. Certain parts of physics contain real and unavoidable difficulties. These have not been slurred over, nor have those portions of the subject which contain them been omitted. It has been thought more serviceable to the student and to the teacher who may have occasion to use the book to face such difficulties...
