So, to facilitate the students in this we have released this Handbook of Physics. This book has been prepared to serve the special purpose of the students, to rectify any query or any concern point of a particular subject. This book will be of highly use whether students are looking for a quick revision before the board exams or just before other examinations like Engineering Entrances, Medical Entrances or any similar examination, they will find that this handbook will answer their needs admirably. This handbook can even be used for revision of a subject in the time between two shift of the exams, even this handbook can be used while travelling to Examination Centre or whenever you have time, less sufficient or more. The format of this handbook has been developed particularly so that it can be carried around by the students conveniently. The objectives of publishing this handbook are : — To support students in their revision of a subject just before an examination. — To provide a focus to students to clear up their doubts about particular concepts which were not clear to them earlier. — To give confidence to the students just before they attempt important examinations. However, we have put our best efforts in preparing this book, but if any error or what so ever has been skipped out, we will by heart welcome your suggestions. A part from all those who helped in the compilation of this book a special note of thanks goes to Ms. Yojna Sharma of Arihant Publications.
