Department of Physics has well equipped Physics laboratory for B.Tech students. The Physics experiments are performed by the students of all Engineering branches. The experiments are based mainly upon Optics, Electrostatics and Electricity&Magnetism, Modern Physics and Solid State Physics which are the parts of theory syllabus. Students will be required to perform at least 10 experiments out of the list in each semester.
