Description: In this session, we do more standing wave problems. The focus is on the role of boundary conditions at the intersection of two continuous media with different physical characteristics.

Instructor: Prof. Wit Busza

See the Video Index tab for a list of problems reviewed in this video.

  • The taut string fixed at both ends from the previous session is now replaced by two connected strings, each with a very different density. The lowest two normal modes are found by inspection.
  • A problem similar to the above, but this time the strings are replaced by rods which vibrate longitudinally and different boundary conditions are chosen.
  • Calculation of the normal modes of vibration of the air in a room. It is a standing wave problem in 3D.
