A flautist is playing a flute as discussed in Example 6, but now the temperature is 305 K instead of 293 K. As a result, the speed of sound is no longer 343 m/s. Therefore, with the length calculated in Example 6, the note middle C does not have the proper fundamental frequency of 261.6 Hz. In other words, the flute is out of tune. To adjust the tuning, the flautist can alter the flute's length by changing the extent to which the head joint (see Figure 17.21) is inserted into the main stem of the instrument. To what length must the flute be adjusted to play middle C at its proper frequency?
