A 40-cmcm-long tube has a 40-cmcm-long insert that can be pulled in and out. A vibrating tuning fork is held next to the tube. As the insert is slowly pulled out, the sound from the tuning fork creates standing waves in the tube when the total length LL is 42.5 cmcm , 58.5 cmcm
What is the frequency of the tuning fork? Assume velocity of sound = 343 m/s
