11.2: Reflection of Waves at a Boundary

  • Page ID
  • Waves on a string form standing waves because the wave reflects from each end of the string where there is a fixed node. How do standing waves form in a tube full of air? This section shows that waves reflect from the end of a tube and that this reflection can be of two types, depending on whether the boundary is 'soft' or 'rigid'.
