Day 7

Spaced Revision

Come back to Superposition of Waves-2 : Stationary (Standing) Waves : Vibration of Air Columns after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • A bounded medium has definite boundaries.
  • Only certain frequencies are produced in a bounded medium.
  • Free end reflection causes no phase change.
  • Stationary waves are produced by superposition of opposite travelling waves.
  • Nodes are points of zero displacement.
  • Antinodes are points of maximum displacement.
  • A closed pipe has a node at the closed end and an antinode at the open end.
  • Only odd harmonics are present in a closed pipe.
  • Fundamental tone means first harmonic.

Common Mistakes to Avoid

A free or open end causes a phase change of pi on reflection.

A closed organ pipe has antinodes at both ends because sound can move out of the pipe.

Closed organ pipes produce all harmonics just like open pipes.

Memory Tips

Bounded medium is essential for stationary waves

Free end reflection has no phase change

Rigid end reflection has a phase change of pi

Stationary wave creation by superposition
