The program in physics is designed to provide opportunities for the undergraduate student to develop the skills essential for graduate school, industry, government service and the teaching of physics. The physics curriculum offers two degree tracks designed to prepare a student for employment or further study in physics or in the various engineering fields, such as, but not limited to, electrical and mechanical engineering. Students with an interest in biophysics may take a minor in biology, or take a set of recommended biology electives. Physics majors have gone on to careers in physics, civil, electrical, & mechanical engineering, biomechanical engineering and medicine. The department also provides a fundamental physics foundation for other science disciplines. Physical science courses are available to those not majoring in the sciences.

A chapter of Sigma Pi Sigma, National Physics Honor Society, has been established to give recognition to outstanding students.

The Physics Department operates the SBU Observatory, which is equipped with an 11 inch Schmidt-Cassegrainian telescope. Interested students may participate in the Orion Astronomy Club.
