## Homework Statement

A 50-cm-long wire with a mass of 1.0 g and a tension of 440 N passes across the open end of an open-closed tube of air. The wire, which is fixed at both ends, is bowed at the center so as to vibrate at its fundamental frequency and generate a sound wave. Then the tube length is adjusted until the fundamental frequency of the tube is heard. What is the length of the tube?

Speed of sound is 340 m/s

## Homework Equations

½L √(T/µ) = f

Vsound = 340 m/s

## The Attempt at a Solution

I keep getting 0.362m or 36.2 cm but it is incorrect..any help?
