26PRACTICE PROBLEM
To tune notes of varying pitches, most wind instruments have a mechanism for adjusting the length of the air column. A musician adjusts the length of his open-open instrument to produce a fundamental frequency of exactly 494 Hz on a day when the speed of sound in the air was 343 m/s. The concert was held on a different day. The speed of sound in the air decreased to 338 m/s. How much the musician must adjust the length of his musical instrument to obtain the same frequency obtained during the day?
