## Resonance in Pipes

Standing waves form in pipes at specific frequencies determined by the pipe length and boundary conditions.

### Open Pipe (both ends open)

**f_n = n * v / (2L)** where n = 1, 2, 3, ...

### Closed Pipe (one end closed)

**f_n = n * v / (4L)** where n = 1, 3, 5, ... (odd harmonics only)

Ejemplo Resuelto

Fundamental frequency of a 0.5 m open pipe at 343 m/s.

  1. f_open = n * v / (2L)
  2. f_open = 1 * 343 / (2 * 0.5)
  3. f_open = 343 Hz
  4. f_closed = 1 * 343 / (4 * 0.5)
  5. f_closed = 171.5 Hz
