The Wavewatcher's Companion by Pretor-Pinney, Gavin (2010) Hardcover

Watching breakers roll onto a Cornish beach, the author of the best-selling Cloudspotter's Guide decided to find out where they came from. The result was this erudite and entertaining book. After describing the types of ocean wave and the forces that drive them, he explains the invisible waves that shape our universe - light waves, sound waves, shock waves - and those, such as radio and X-rays, that we harness in our technology.
