This new full colour edition of the established text for standard grade physics students is also updated in a number of ways. The chapter on telecommunication has been updated to fully match the syllabus requirements, and that on health physics has also been revised. Key equations have been added at the end of every chapter, together with summaries which will be ideal for revision. There are many new colour photos to illustrate more recent applications of the key theories throughout. A Without Answers edition is also available.
