Description The ringing notes of an electric guitar, the ripples after you've thrown a rock in the water, even the way a microwave oven cooks your food. These are all examples of what waves can do. A wave is one way that energy travels through space and matter. This book simplifies complex physical science topics so young readers can understand them more easily. Real-life examples of how people use waves for science, art, and more help readers see how waves are all around us.
