"This exciting title introduces readers to the concept of a wave and the patterns and properties common to both light and sound waves. Clear text and detailed diagrams combine to demonstrate the cause-and-effect relationships involved in the properties of amplitude, wavelength, and frequency. A link to interactive activities online plus an activity in the book allow readers to explore key concepts close up by creating their own wave models."--

Examines different kinds of electromagnetic waves, including radio waves, microwaves, light, x-rays and gamma rays.

Introduces electromagnetic and mechanical waves, discussing the properties of waves, the electromagnetic spectrum, and vibrations.
