The authors feel great pleasure in presenting thoroughly revised and enhanced Seventeenth Edition of the book encouraged by the overwhelming response of the readers.
The present edition is strictly in accordance with the latest CBSE syllabus. In the revised syllabus of 2019-20 CBSE has removed a topic ‘Ray Optics’. Each chapter of this book carries quite a good number of solved as well as unsolved numericals. Guidelines for NCERT Problems with their solutions have also been added for the benefit of the students. At the end of each chapter, a large number of questions are given which are divided into different categories, such as Very-Short Answer Type, Short-Answer Type, Long-Answer Type, Numericals. The order of questions and numericals in each category is strictly the same as the order of topics in the text matter. Except Long-Answer type questions, all other questions have been supported with answers or hints as necessary. Under the heading ‘For Different Competitive Examinations’, Single Digit Integer Answer Type Questions, Matching-List Type Questions, Assertion-Reason Type Questions, Linked Comprehension Type Questions, Objective and Multiple-Choice Type Questions have been divided in to two categories : [A] Single Correct Answer Type and [B] Multiple Correct Answer Type. These questions have been supported by hints or solutions. Entire book has been throughly revised to make it free from errors.
