1. The problem statement, all variables and given/known data
A tube of air is open at only one end and has a length of 1.7 m. This tube sustains a standing wave at its third harmonic. What is the distance between one node and the adjacent antinode? 2. Relevant equations v = f (lambda) 3. The attempt at a solution If it's in the third harmonic, that means the length of the tube is equal to 1.25 wavelengths. So, 1.7 / 1.25 = 1.36. The distance between an antinode and the adjacent node is .25 lambda, so 1.36 * .25 = .34m. So .34m is the answer.

If it's in the third harmonic, who many nodes and anti nodes are formed in the tube?

Can someone tell me what I did wrong?

In the tube closed at one end, third harmonic is the first overtone. So L = 3*lambda/4
