Experimentation is inevitable part of actualizing theories. To inculcate the mathematical aptitude, habit of experimentation and self learning, CBSE conducts practical exams along with theoretical exams. CBSE Class 12th, physics lab manual has been prepared strictly according to CBSE guidelines. All the experiments in this manual have been given in simple, lucid and interactive manner. The theory given with each experiment is a very special feature of this lab manual. It gives complete understanding of each term concept and definition, etc. so that the students need not to refer their textbooks or any other books. Viva-voce questions are given with each experiment test students’ understanding of related experiments. The book serves as the step by step guide for conducting experiments explaining the relevance of each step with accurate diagrams, observations and calculations with each experiment.
