Question

A tube 1.20m long as closed at one end. A stretched wire is placed near the open end.  The wire is 0.330m long and has a mass of 9.60 g. It is fixed at both ends and oscillates in its fundamental mode. By resonance, it sets the air column in the tube into oscillation at the column A tube 1.20m long as closed at one end.

Explanation / Answer

The speed of sound in air is about 340m/s.

In a closed tube such as you have described, the fundamental frequency occurs when you have a quarter wavelength in the tube so L=
