Sound Standing Wave in Kundt's Tube

Kundt's tube experiment is used to invest sound standing waves in a transparent tube.

The wave patterns are displayed by tiny Styrofoam balls. The resultant graphic profile could be easily visualized by the separated group of Styrofoam balls distributed inside the pipe.

That will also lead the user to understand the characteristic of standing wave such as the accessed wavelength, fluctuated amplitude corresponding to individual resonance frequency.

Task:

- Observe the sound standing wave in a resonance tube. And determine the nodes and antinodes.

- Detemine the wavelength from the nodes and antinodes. Then calculate the traveling velocity of sound wave

- Investigate the difference of resonance between open and closed pipe 

This set Including:

- Resonance Tube 1000mm, dia. 60mm

- Audio Generator 0-2000Hz. 

- Student AC/DC Power Supply 0-3-6-9-12V (Optional)

- Loud-speaker with amplifier, aperture 60mm, adjustable volume

- H Shaped Standing Base (Optional)

- Metal holder for tube

- Tiny foam
