LIGHT: THE VISIBLE SPECTRUM AND BEYOND
A wonderful book to understand the different parts of the electromagnetic spectrum, through images and examples: Light, The visible spectrum and beyoind, by Arcand and Watzke Worth having, and of mandatory reading by anyone interested in science... Read at Amazon: "Light allows us to see everything around us, but humans can only see a sliver of all light, known as the electromagnetic spectrum. Here, Kim Arcand and Megan Watzke present the subject of light as never before. Organized along the order of the electromagnetic spectrum, each chapter focuses on a different type of light. From radio waves, harnessed for telecommunications, to X-rays, which let us peer inside the human body and view areas around black holes in deep space, Arcand and Watzke show us all the important ways light impacts us. An introductory chapter describes what light is and how it behaves, while hundreds of full-color photographs and illustrations demonstrate concepts and make for a stunning book that's a joy to read and browse."
