Physics finds a wide application in industry, atomic and space organizations, forensic science, meteorology, electronics, design & development engineering, research laboratories. It also has considerable commercial and military value. Physicists are mainly involved in (R&D) research and development in specialized branches such as elementary particle physics, astrophysics, nuclear physics, biotechnology, etc. A growing number of physicists specialize in biophysics, chemical physics, radio physics, astrophysics and related sciences. Besides going in for research, you could also teach in colleges/universities for which the minimum requirement is M.Sc Physics and qualifying the UGC-CSIR NET for lectureship and JRF.
