About the book

Book 3 covers the topics of "Wave Motion", which lays the foundation of physics and the concepts are also used in other sections of the syllabus. Moreover, this section carries a significant weight in the HKDSE examination. It takes time for students to grasp the concepts and master the necessary skills in solving problems. 

Some examination questions on this section cover integrated topics and require candidates' ability to comprehend an unfamiliar situation and to apply suitable knowledge in solving problems. In this book, although topics are grouped clearly in different chapters, some questions in a later chapter require application of knowledge learned in previous chapters. This will help candidates to consolidate their knowledge and to build up their confidence in tackling problems demanding higher order skills.
