C. 3x/2
D. 2x
the correct answer is answer D.
Homework Equations
Pipe with two ends open
λn= 2L /n
Pipe with one end open and one end closed
λn= 4L/n
The Attempt at a Solution
At the positions of maximum loudness, there must be an antinode, but the water acts like a closed pipe so there should be a node at the surface of the water. If there is an antinode at the positions of maximum loudness the fundamental frequency would have a wavelength in distance x of λ/2. but that doesn't make sense since there should be a node so now I am confused and also don't understand how to know how many loops there should be.
