8.03 Physics III: Vibrations and Waves

8.03 Physics III: Vibrations and Waves (Fall 2004, MIT OCW). Instructor: Professor Walter Lewin. In addition to the traditional topics of mechanical vibrations and waves, coupled oscillators, and electromagnetic radiation, other interesting topics are covered in this course: musical instruments, red sunsets, glories, coronae, rainbows, haloes, X-ray binaries, neutron stars, black holes and big-bang cosmology.
