Exploring The Spectrum

The entire electromagnetic spectrum is covered in this book, everything from the short radioactive waves used to sterilize male screw flies so the female lays sterile eggs; to the long-wave radio frequencies that penetrate the soil, control and enhance root growth and the immune system of plants and animals. Explains not only the visible-light spectrum, but also the invisible high-energy nuclear and low-energy infrared and radio portions of the electromagnetic spectrum.
