The science of Physics explores the basic properties of matter and the forces which act upon matter. Using precise experimental measurements, physicists formulate laws which describe the observed behavior of the physical world. In the Bachelor of Science program, students gain experience in dealing with a broad range of physical phenomena. They learn the laws of Physics and develop the theoretical and experimental skills necessary to apply these laws to a wide range of phenomena. With a Bachelor of Science degree in Physics, a student is prepared to do design and development work in industry or a government laboratory or to teach high school science and Physics. Students planning to do Physics research or to teach at the university level should study further and obtain an M.S. or Ph.D. degree.

GradTrac is available to Standard Physics majors. See more information about GradTrac.

Honors Curriculum—Academically qualified students in this department are encouraged to complete an honors curriculum in University Honors, Departmental Honors, or General Honors. All Honors students must complete the one-hour honors colloquium (G H 299). General Honors includes General Honors coursework. Departmental Honors includes honors work in the major. University Honors combines Departmental and General Honors. View more information about honors curricula or visit the Centennial Honors College website at wiu.edu/honors.

Integrated Baccalaureate and Master’s Degree Program—An integrated baccalaureate and master’s degree program is available for the Bachelor of Science in Physics: Master of Science in Physics. An integrated degree program provides the opportunity for outstanding undergraduates to earn both degrees in five years. Please refer to the Graduate Studies catalog for details about the integrated program.
