B.Sc. Practical Physics

B.Sc. Practical Physics by CL Arora

---

Book Summary:

This book has been written to meet the requirements of students of the New Three Year B.Sc. Degree Course in Indian Universities. It contains experiments on Mechanics and Properties of Matter, Heat and Statistical Physics, Optics, Sound, Magnetism, Electricity, Atomic and Molecular Physics, Nuclear Physics, Electronics and Solid State Physics according to the latest syllabi for the new three year degree course laid down by the Panjab University, Chandigarh; Guru Nanak Dev University, Amritsar; Panjabi University, Patiala; Kurukshetra University, Kurukshetra; Maharishi Dayanand University, Rohtak and Himachal Pradesh University, Simla in particular and other Indian Universities in general. The text has been thoroughly revised, rewritten and brought up-to-date by adding all the new experiments included in the latest syllabi.

Audience of the Book :

This book Useful for B.Sc. Practical Physics Students.

Salient Features:

1. According to the latest system of examination adopted by most of the Indian Universities, the candidates are required to write the theory of the experiment before starting the experimental work. With this aim in view, a brief and relevant theoretical discussion of the experiment has been included in the body of the experiment properly so that a student actually reads and understands it before he starts working. In addition, the detailed theory has also been given separately wherever necessary.

2. A brief description of the apparatus required during the experiment has been given and the range of various measuring instruments has been specified so that the observations can be
taken with a fair degree of accuracy.

3. The procedure has been divided into steps so that a student may be able to proceed systematically even without the direct guidance of a teacher.

4. The system of recording the observations in a tabular form has been encouraged throughout the text so that various readings can be compared at a glance.

5. The precautions have not only been given at the end of the experiment but also have been included in the instructions so that a student actually observes them even when he is performing the experiment.

6. As there is a growing tendency on the part of examiners to ask oral questions about the experiments done by a student in the examination, a number of such questions have been given
at the end of each chapter for practice.

It is hoped that with all these and other features this book will prove very useful for the students.
