This text on Practical Physics has been primarily written to cover all the experiments as per the revised syllabus for 2017-18 prescribed for Second Year B.Sc. Semester III (Physics) by the University of Mumbai. It is our endeavour to present the experiments in proper form and also suggest to set up Basic skill experiments. We reasonably feel that this text will enable students to perform experiments with confidence and understanding.
Theoretical aspect has been additionally given for which will help students to understand the experiment in proper perspective.
The procedure of each experiment is given sequentially. The observation table are given for proper presentation of various measured quantities.
All the necessary diagrams are given for proper setting up of the apparatus. All the required circuit diagram, graphs, formulae are provided. Precautions which are to be taken while performing experiments are given wherever necessary.
