Sound And Light

Uses activities and experiments to introduce the properties of light and sound.

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.

This undergraduate textbook aids readers in studying music and color, which involve nearly the entire gamut of the fundamental laws of classical as well as atomic physics. The objective bases for these two subjects are, respectively, sound and light. Their corresponding underlying physical principles overlap greatly: Both music and color are manifestations of wave phenomena. As a result, commonalities exist as to the production, transmission, and detection of sound and light. Whereas traditional introductory physics textbooks are styled so that the basic principles are introduced first and are then applied, this book is based on a motivational approach: It introduces a subject with a set of related phenomena, challenging readers by calling for a physical basis for what is observed. A novel topic in the first edition and this second edition is a non-mathematical study of electric and magnetic fields and how they provide the basis for the propagation of electromagnetic waves, of light in particular. The book provides details for the calculation of color coordinates and luminosity from the spectral intensity of a beam of light as well as the relationship between these coordinates and the color coordinates of a color monitor. The second edition contains corrections to the first edition, the addition of more than ten new topics, new color figures, as well as more than forty new sample problems and end-of-chapter problems. The most notable additional topics are: the identification of two distinct spectral intensities and how they are related, beats in the sound from a Tibetan bell, AM and FM radio, the spectrogram, the short-time Fourier transform and its relation to the perception of a changing pitch, a detailed analysis of the transmittance of polarized light by a Polaroid sheet, brightness and luminosity, and the mysterious behavior of the photon. The Physics of Music and Color is written at a level suitable for college students without any scientific background, requiring only simple algebra and a passing familiarity with trigonometry. The numerous problems at the end of each chapter help the reader to fully grasp the subject.

In Waves of Light and Sound, students will learn about electromagnetic and mechanical waves, the properties of waves and sounds, pitch, amplitude, and much more. Readers will love discovering new information in this chapter book while also reinforcing learned skills with comprehension and extension activities. The Let’s Explore Science series allows readers to dive into the world of fascinating science-related topics while strengthening reading comprehension skills. Each 48-page title features full-color photographs, real-world applications, content vocabulary, and more to effectively engage young learners.

My littlest girl has always been a bit peculiar. It was nothing I could ever put a finger on, but I always knew there was something inside her that made her a different kind of special. A deeper kind. K'acy's got a light around her, one that'll just about knock you over, especially if you don't see her coming. She's got music in her soul, too. Deep, resonating music that echoes and hums, just like the notes that come from the bass guitar she's had attached to her hip since the day she turned thirteen years old. She's got a hell of a secret, yes, but she does what she's got to do to make it one worth having. She takes care of people. She changes their stories. I spent my life telling both of my girls that you always gotta do what's right, even when it hurts, and it makes me proud to know she was listening. I saw the way she looked at that boy on the day they met, and I knew right then that things were going to change. Two different people from two different worlds is nothing but a recipe for heartbreak, and when the lies pile higher and higher, it can change a person into something they're not. It took me dying all those years ago to finally figure out just exactly how special my K'acy really is, and even though I'm not with her anymore, I don't want that boy and his family to change her. I want her to keep doing what's right, even when it hurts. Because that's who she is inside. That's her deeper kind of special. **This stand-alone novel by Claire Wallis is intended for mature readers age 17 and up**
