Question
**Illustration Description:**

The image illustrates an experimental setup involving a glass tube, a piston, and cork particles. The system is used to demonstrate standing waves and resonance.

**Components:**

1. **Piston:**
   - Located on the left side of the glass tube.
   - Connected to a sound source that vibrates at a frequency of 400 Hz.

2. **Glass Tube:**
   - Positioned horizontally and measures 123 cm in length.
   - Contains the moving piston on one end and is open at the other end.

3. **Piles of Cork Particles:**
   - Distributed along the length of the glass tube.
   - Indicate positions of the antinodes where the air displacement is maximum.

**Functionality:**

- The piston generates sound waves that travel through the air in the glass tube.
- These sound waves reflect back and forth, creating standing waves.
- The cork particles accumulate at positions of antinodes due to the larger air movement at these points.

This setup visually demonstrates the concept of resonance and the formation of standing waves within a closed environment. It is especially useful for educational purposes in physics to illustrate wave behavior in a controlled experiment.

### Kundt's Tube Experiment

In 1866, the German scientist Adolph Kundt developed a technique for accurately measuring the speed of sound in various gases. A long glass tube, known today as a Kundt's tube, has a vibrating piston at one end and is closed at the other. Very finely ground particles of cork are sprinkled in the bottom of the tube before the piston is inserted. As the vibrating piston is slowly moved forward, there are a few positions that cause the cork particles to collect in small, regularly spaced piles along the bottom.

The figure shows an experiment in which the tube is filled with pure oxygen and the piston is driven at 400 Hz.
