This introductory text emphasises physical principles, rather than the mathematics. Each topic begins with a discussion of the physical characteristics of the motion or system. The mathematics is kept as clear as possible, and includes elegant mathematical descriptions where possible. Designed to provide a logical development of the subject, the book is divided into two sections, vibrations followed by waves. A particular feature is the inclusion of many examples, frequently drawn from everyday life, along with more cutting-edge ones. Each chapter includes problems ranging in difficulty from simple to challenging and includes hints for solving problems. Numerous worked examples included throughout the book.Die Einführung wendet sich an Physikstudierende im Grundstudium und präsentiert dementsprechend viele Fragen, Aufgaben und Übungen. Auf Mathematik wird so weit wie möglich verzichtet. Primäres Ziel ist es, Entwicklung und Aufbau des Wissensgebiets verständlich darzustellen.
