## Physics

The Physics major offers the same broad scope of study as would be found at a larger research university. In addition to basic offerings in classical mechanics, electricity and magnetism, relativity, and quantum physics, the curriculum includes courses in digital and analog electronics, solid state physics, thermodynamics and statistical mechanics, special topics courses exploring areas of particular interest, and advanced laboratories exploring phenomena as diverse as physical optics, x-ray diffraction, spectroscopy, and radioactivity.

At the same time, Randolph-Macon's focus on undergraduate education means that students enjoy individualized attention, mentoring, and support from faculty. Research apparatus intended for and available to students for their use. The college supports an active student research program, and many students culminate their studies with a two-semester senior project in an area of particular interest. Recent investigations have included an automated detector to study diffuse solar insolation, an analysis of the frequency components of human voices as a prelude to computerized voice recognition, effects of radiation damage of high Tc superconductors, and a combined experimental and theoretical study of the Rubens' flame tube.

Demand for graduates in STEM (science, technology, engineering, and mathematics) fields is very high. Recent figures from the American Institute of Physics indicate that 95% of 2009-2010 graduates with a bachelor's degree in the field of physics were either employed or enrolled in a graduate program, with starting salaries for these graduates in STEM jobs in the private and government sectors ranging from $38,000 to $60,00.
