This book is written for first year undergraduate engineering and basic science students of various technical universities of India, in particular Amity University, Gautam Buddha Technical University (formerly UP Technical University) and Indraprastha University. Also, this book covers experiments prescribed in B.Sc. courses of different Indian Universities. The experiments are written in simple and lucid manner so that students can easily comprehend and perform the experiments with understanding and care. The related theory and viva-voce questions with answers, given with each experiment make the book useful to the students. Introductory information about the laboratory instruments is an added feature of the book.
