Objectives Students completing this subject should be able to explain, use and apply basic concepts of physics in areas such as electron and radiation physics, optics and instrumentation to biomedical and environmental contexts such as the human body, animals, plants and the biosphere; use the concepts and principles of physics to demonstrate increased understanding of how light and radiation interact with body systems and how optical and electronic instruments extend knowledge of body and environment systems; carry out reliable measurements, analyse data, interpret physical phenomena; write scientific reports in the context of simple experiments in radiation physics, optics and instrumentation.
Synopsis This subject emphasises biological applications of physics and follows PHS1031. It comprises three theory units supported by related experimental work. (1) Electron and radiation physics: waves and particles, the cathode ray oscilloscope, electron microscope, x-rays, nuclear radiations and isotopes, dosimetry and shielding, biological effects, CT, PET and MRI imaging. (2) Optics: the visible spectrum, reflection, refraction, lenses and image formation, aberrations, human eye and defects, polarisation and microscopes, diffraction and resolution. (3) Instrumentation: waves, reflection, standing waves, resonance, sound and hearing, Doppler effect, ultrasound imaging, transducers for sound, light, temperature and strain, power supplies, amplifiers, recorders, instrumental parameters, sensitivity, response time and bio-environmental applications
Assessment Examinations (3 x 1.5 hours): 65% + Laboratory work: 20% + Tests: 15%
