Description: The authors have examined carefully a number of Indian Universities and evolved a common minimum laboratory programme and the result is this compilation. The experiments chosen are the minimum required for undergraduate programmes. Some experiments have been purposely included so that they can be covered at demonstration level and can be given as exercises at the postgraduate level. The authors have attempted to assemble the list of experiments from their experience and also have drawn upon the experience of the students who have undergone these laboratory courses and felt the inadequacy of the existing curriculum.
