Introduction

Wave Motion is the fifth among the several volumes of Physics in 24 hours series, which is specially written for students who sit for the HKDSE Physics Examination. Notes and examples in this book are in line with the latest fine-tuned syllabus of HKDSE Physics Examination (2016 onwards). Detailed and comprehensive explanations on difficult concepts are given in this book. The point-form notes are the ultimate quick revision tool for students. Multiple choice questions at the end of every topic provide an effective way in checking study progress. Bonus mock examination questions on the topic “Wave Motion” are provided at the end of the book. These questions are tailor-made in resemblance to the style and format of their public examination counterparts.
