Synopsis
Every second of every day, the sun emits wave after wave of radiation hurling toward our planet. Even though we can't see most of this radiation with the naked eye, scientists have learned how to use these invisible waves to our advantage. From infrared systems to guide missiles to ultraviolet-sterilized laboratory work areas, visible light's closest neighbors on the electromagnetic spectrum have a lot to offer us. This book explores the science and discovery of infrared and ultraviolet radiation, as well as the ingenious ways scientists and engineers have used them, including in common household devices such as remote controls for our televisions and in cutting-edge medical treatments.
Reviews
Gr 7 Up—Each of these books begins with an overview and how the title topic fits into the spectrum. Helpful diagrams and images show how infrared is used, the frequencies of microwave transmissions, and other details. Plentiful sidebars discuss related topics such as pinhole cameras, Blu-ray players, or polarized sunglasses. Early researchers in each area, including Newton, Roentgen, and Faraday, are described with their experiments and findings. Along with the history, there is also in-depth discussion of current uses and applications, like Gamma Knife surgery and remote sensing technology, as well as future uses, such as providing LiDAR sensors for self-driving cars. Back matter includes extensive chapter notes, a glossary, and a suggested reading list. VERDICT A detailed set perfect for use in physics classes or for science project research.
