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.
