This course includes some experimental work that supports the lecture material. Role within programme and connections to other courses. Oscillations and waves are key elements to understanding many subfields and applications of physics. Acoustics, optics and electromagnetism (telecommunications) are obvious examples, but waves are also essential to understanding quantum mechanics (the Schrödinger formalism), some atmospheric phenomena, seismic phenomena and fluid mechanics. Content. Waves, applications to optics and acoustics.
