For open-ended tubes:Thanx!!!
Can u give this a read and tell me if I'm wrong?
Is it right 2 say that:
For one-end open tube:
Half a loop is formed, with node at closed end and anti-node at open end.
f = V/4L (Fundamental frequency)
More waves formed in this tube will always be half, one nd a half, etc loops.
And will the anti node ALWAYS be at the open end in one-end open tube?
ANyway, for other frequencies, we'll multiply V/4L by 3 (coz next wave will b 1.5 loops), 5 and so on.
For closed end:
Always full loop is formed. But will the anti-nodes again always be at open ends?
And fundamental frequency will b V/2L.
We'll multiply it by 2, 3, 4 etc when more waves are formed. (Two loops, three and four and so on...)
Can u confirm if what I've written is correct?
One full loop is always formed
The number of loops can be changed using the frequency..
Yeah, the loops will be half, one and a half etc.. and 1/4lambda, 3/4lambda, 5/4lambda respectively.
I'm not very sure of f = V/4L, but I usually count the number of loops, and add the corresponding lengths i.e 1/4lambda, 1/2 lambda and so on.
Yes, an anti-node is always at the open end of the tube and a node is at the closed end.
Closed at one end:
A half loop is formed
Again, the number of loops depends on the frequency.
Yes, anti-nodes will always be at the open ends.
Regarding f = V/4L, I've uploaded a useful powerpoint.. hope it will answer your questions.
Best of luck!
