[QUOTE="EF17xx, post: 5967807, member: 635003"] [h2]Homework Statement [/h2] [ATTACH=full]222892[/ATTACH] The question is as follows: The distance between the two positions of maximum loudness is x What is the wavelength of the sound emitted by the tuning fork ? A. x/2 B. x C. 3x/2 D. 2x the correct answer is answer D. [h2]Homework Equations[/h2] Pipe with two ends open λn= 2L /n Pipe with one end open and one end closed λn= 4L/n [h2]The Attempt at a Solution[/h2] 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.
