Energy in Action: Electromagnetic Energy

Product Description

What do radios, microwave ovens and X-ray machines have in common? They all use different forms of electromagnetic energy to do work. In Electromagnetic Energy, learn that cosmic rays from space and visible light are also part of the family of energy waves known as the electromagnetic spectrum. Discover that electromagnetic energy travels in waves through space and can also move through solid materials. Fast-paced visuals and dynamic graphics help explain that the size of the waves determines their position in the spectrum as well as how much energy they contain. A fun demonstration illustrates that magnetic and electric forces are different aspects of electromagnetic energy, while a hands-on investigation proves that a light bulb radiates both visible light and infrared waves.
