electromagnetic waves

Waves and wave motion are the keys to communication but they can also help us understand the movement of storms and of planets.

Quantum physics is the study of matter at the subatomic level, and it gives us an understanding of the basic structure of the universe.

This book examines waves that travel through a medium and electromagnetic waves that do not require a medium and describes their characteristics, the ways in which they behave, and their practical application in our daily lives.

Examines questions about light and the electromagnetic spectrum, describes the physical properties of light, explores the spectrum of energy and the uses of radio waves, x-ray waves, and visible light, and traces the history and inner workings of analog and digital television systems.

Introduces young readers to the basics of light, discussing what it is and how it works.

Displays the facts about energy and waves, discussing energy sources, the power grid, splitting atoms, sound waves, energy use, and saving energy. Includes charts, maps, illustrations, and timelines.

Photographs, illustrations, and text describe what radiation is and explain the different types of radiation.

An explanation of the nature of the electromagnetic spectrum, the scientific investigations that led to our understanding of it, and its role as a tool of science.

Contains a collection of articles that discuss trends in the study of sound and electromagnetic waves, covering the natural world, human constructions, and various applications of different waves that transport energy away from its source.

An introduction to the world of physics, focusing on light, sound, and electricity, with explanations of related scientific terms, experiments and activities, study guides, and links to over one hundred related Web sites.
