0.342m/4 = 0.0855 m

can you please list all the formulas necessary related to this unit.

15. IrishBoy123

the closed pipe [closed at one end] has a constraint at the closed end, which must be a node. the fundamental resonance occurs when $$\lambda = 4L$$

16. IrishBoy123

as $$v = f.\lambda$$, then $$\lambda_1 = \frac{v}{f}$$ and $$L_1 = \frac{v}{4*f}$$

17. YumYum247

can you please tell me how a fundamental resonance occur when λ=4L with a quick sketch!!!

18. IrishBoy123

look at this: http://hyperphysics.phy-astr.gsu.edu/hbase/waves/clocol.html this site is generally great for illustrations/pictures/diagrams

oh i got it.... o_o

21. YumYum247

so the minimum length in this case would be the length of the fundamental

22. YumYum247

ok let me watch a tutorial on this topic and nopefuly it'll help me clearfy the misconceptions i have.....Thanks tho!!

23. IrishBoy123

yes. get you're head around the science and the formulae you can build .... the locations of the nodes are key.
