Practical Physics

Practical Physics by Dr. A. B. Bhise, R. B. Bhise

Book Summary:

We are happy to place this book “S.Y.B.Sc. Physics Practical” in the hand of B.Sc. students and teachers of Savitribai Phule Pune University. This book envisages the revised syllabus which is implemented from the academic year 2014-15. It is general impression of physics students that physics practicals are very difficult, hence the experimental matter is prescribed in a simple and lucid manner with the help of neat and clear figures of instruments.

This book gives a brief description of physics experiments which are chosen as per the latest curriculum. The experiments include oscillations, waves, sound, optics, electronics, instrumentation, computer and demonstration. Each experiment is discussed with Aim, Apparatus, Diagram, Procedure, Observation, Observation table, Formulae and Results. The theory of experiment is presented in brief in the principle with necessary formulae and their explanation.

At the end of each experiment necessary Oral Questions, Tables and Graphs are included. We think that the students will find this book most useful while performing the experiments.

Audience of the Book :

This book Useful for B.Sc students.
