Key Topics to Revise

1

1. Bounded Medium and Reflection of Waves

  • A bounded medium has definite boundaries separated from other media by distinct surfaces.
  • A bounded medium is essential for the formation of stationary waves.
  • A wave reflected from a free or open end does not suffer any phase change.
2

2. Stationary Waves: Formation and Properties

  • A stationary wave is formed by superposition of two identical progressive waves of the same speed moving in opposite directions.
  • Stationary waves do not transmit energy in the medium.
  • The amplitude is zero at nodes and maximum at antinodes.
3

3. Closed Organ Pipe

  • A closed organ pipe is closed at one end and open at the other end.
  • The closed end is always a node and the open end is always an antinode.
  • A closed pipe produces only odd harmonics.
4

4. Open Organ Pipe

  • An open organ pipe is open at both ends.
  • Each open end is an antinode.
  • An open pipe produces all harmonics, both even and odd.
