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. Teacher's guide available.
Waves are everywhere in our daily life. We all experience sound and light with our ears and eyes, we use microwaves to cook, and radio waves are transmitted from and are received by our cell phones. These are just some examples of waves that carry energy from point A to B. However, we may not know details of the physics underlying all these waves. It is important to understand the mechanisms that generate wave dynamics for a given system. It is not straightforward to explain how an electromagnetic field becomes oscillatory and propagates as a wave. Waves sometimes represent the underlying dynamics of observed phenomena at a fundamental level of physics. This book is designed to explore these mechanisms by discussing various aspects of wave dynamics from as many perspectives as possible. The target audiences are undergraduate students majoring in engineering science and graduate students majoring in general engineering. Going beyond the typical approach to learning science, this book discusses wave dynamics and related concepts at various levels of mathematics and physics, sometimes touching on profound physics behind them. This book was written to help readers learn wave dynamics on a deep physical level, and develop innovative ideas in their own fields.
Like rocket science or brain surgery, quantum mechanics is pigeonholed as a daunting and inaccessible topic, which is best left to an elite or peculiar few. This classification was not earned without some degree of merit. Depending on perspective; quantum mechanics is a discipline or philosophy, a convention or conundrum, an answer or question. Authors have run the gamut from hand waving to heavy handed in hopes to dispel the common beliefs about quantum mechanics, but perhaps they continue to promulgate the stigma. The focus of this particular effort is to give the reader an introduction, if not at least an appreciation, of the role that linear algebra techniques play in the practical application of quantum mechanical methods. It interlaces aspects of the classical and quantum picture, including a number of both worked and parallel applications. Students with no prior experience in quantum mechanics, motivated graduate students, or researchers in other areas attempting to gain some introduction to quantum theory will find particular interest in this book.
This text considers waves the great unifying concept of physics. With minimal mathematics, it emphasizes the behavior common to phenomena such as earthquake waves, ocean waves, sound waves, and mechanical waves. Topics include velocity, vector and complex representation, energy and momentum, coupled modes, polarization, diffraction, and radiation. 1974 edition.
Waves and Wave Motion are the keys to communication but they can also help us understand the movement of storms and of planets.
For decades, the surface-plasmon-polariton wave guided by the interface of simple isotropic materials dominated the scene. However, in recent times research on electromagnetic surface waves guided by planar interfaces has expanded into new and exciting areas. In the 1990's research focused on advancing knowledge of the newly discovered Dyakonov wave. More recently, much of the surface wave research is motivated by the proliferation of nanotechnology and the growing number of materials available with novel properties. This book leads the reader from the relatively simple surface-plasmon-polariton wave with isotropic materials to the latest research on various types of electromagnetic surface waves guided by the interfaces of complex materials enabled by recent developments in nanotechnology. This includes: Dyakonov waves guided by interfaces formed with columnar thin films, Dyakonov-Tamm waves guided by interfaces formed with sculptured thin films, and multiple modes of surface-plasmon-polariton waves guided by the interface of a metal and a periodically varying dielectric material. Gathers research from the past 5 years in a single comprehensive view of electromagnetic surface waves. Written by the foremost experts and researchers in the field. Layered presentation explains topics with an introductory overview level up to a highly technical level.
Kids will enjoy learniing about the concept of sound waves in this entertaining book. Readers will learn how sound waves are used for communication and be able to demonstrate this knowledge by creating their own sound devices.
While offering clear, step-by-step explanations of scientific principles, the titles in this series also discuss the social significance and history of each subject using the most up-to-date research on the Physical, Earth, or Life Science addressed.
A brave, intimate, beautifully crafted memoir by a survivor of the tsunami that struck the Sri Lankan coast in 2004 and took her entire family. On December 26, Boxing Day, Sonali Deraniyagala, her English husband, her parents, her two young sons, and a close friend were ending Christmas vacation at the seaside resort of Yala on the south coast of Sri Lanka when a wave suddenly overtook them. She was only to learn later that this was a tsunami that devastated coastlines through Southeast Asia. When the water began to encroach closer to their hotel, they began to run, but in an instant, water engulfed them, Sonali was separated from her family, and all was lost. Sonali Deraniyagala has written an extraordinarily honest, utterly engrossing account of the surreal tragedy of a devastating event that all at once ended her life as she knew it and her journey since in search of understanding and redemption. It is also a remarkable portrait of a young family's life and what came before, with all the small moments and larger dreams that suddenly and irrevocably ended.
