             During the course of applied physics lab manual preparation I have received 
       much support, encouragement, advice and assistance from many people and I am deeply 
       grateful to all of them. 
             I wish to thank and express my gratitude to Dr. Anand Krishna, Principal In 
       charge  G. P., Nawada for his valuable suggestions, inspiring spirits, extensive guidance, 
       constant encouragement, constructive criticism in course of present assignment and for a 
       critical review of the entire manual.  
             I also wish to express heartfelt thanks to all my colleagues for their ceaseless 
       help and co-operation throughout this task. 
             I am greatly obliged to all the non-teaching staff of our institute for providing
