SUMMARY
The shortest air column closed at one end that resonates at a frequency of 440Hz, given a speed of sound of 352m/s, is determined using the formula for the fundamental frequency of a closed tube. The length of the air column can be calculated using the equation L = v / (4f), where L is the length, v is the speed of sound, and f is the frequency. Substituting the values, L = 352m/s / (4 * 440Hz) results in a length of 0.2 meters or 20 centimeters.
