This text is part of the "Oxford Revision Guides" series. These are reissues of the two series "GCSE Revise Through Diagrams" and "Advanced Revision Handbooks", now combined with newly branded covers. The GCSE titles have extra 16-page sections on revision techniques and sample questions for the new GCSE syllabuses, first examined in June 1998. The A-level titles just have new covers, but will be revised in 1999 for the new A-level syllabuses. This book covers the A-level physics syllabus and uses diagrams and concise notes to help students revise.
