Sound and light are two fundamental aspects of experiencing life. For example, sound waves can be reflected off a surface, like an echo, and light can also be reflected, such as when people see themselves in a mirror. Although sound and light waves travel in slightly different ways, vibration is always the source of the motion. This volume in the Physics In Action series explores both types of wavesùfrom how they are generated to how they interact with the world around them. The field of physics is one of the most applicable to a person's everyday life. Knowledge about sound and light therefore helps to answer frequently asked questions, such as why the ocean is blue and why the siren on an ambulance seems to change pitch as it speeds past. Physics in Action explores the science of matter and energy and their interactions. Supplemented by informative color photographs and illustrations, the series drives home fundamental concepts in physics. Practical, real-life examples highlight the text and provide eye-opening insight into the principles that govern Earth and the universe beyond. Book jacket.
