Finding the Speed of Sound
Start with the water near the top, hold a sounding fork over the open end and lower the water slowly. The air column first sounds loudly at length l1, close to a quarter wavelength, and again at l2, close to three quarters. Their difference is half a wavelength, so v = 2f(l2 − l1), and the unknown end correction cancels out.
The End Correction
The antinode at the open end forms a little outside the pipe, so each air column behaves as if it were longer by e. From the same two readings, e = (l2 − 3l1)/2, which comes out at roughly three-tenths of the internal diameter of the pipe.
Other Air-Column and Fork Apparatus
- Resonance Apparatus — another model, pipe and metre scale on a polished wooden board.
- Tuning Fork Set — eight forks, so the speed can be checked at several frequencies.
- Rubber Pad — plain square rubber pad to strike each fork on.
More sound and wave apparatus is in the Physics Lab range.
