Question

1) If a 1.5 m long tube with a 0.5 cm opening has its first resonance point at 44.5 cm, what would be the theoretical location of L3 (in meters with 2 decimal places)?

2) If a 1.5 m long tube with a 0.5 cm opening has its first resonance point at 37 cm, is it possible to hear the third resonance point in the tube?

-No

-Yes

-Not enough information to determine

- None of the above.

(I choose Yes but it was marked incorrect.)
