Yes and yes.

Your question is too vague to offer any more information.

What is the pattern

can u tell me the pattern
 
For a closed-ended column it's:

Ln = (2n-1)Vf
4

For an open-ended column it's:

Ln = nv
2f


Ln: which resonant length your finding.
n: the number corresponding to which resonant length is being found
v: theoretical speed of sound in the particular medium you are using. in air, you can find this with the formula: v = 331.3 + 0.606*(temperature in degrees celcius)
f: frequency of the soundwave in the column.

Hope this helps :smile:
 
Sorry, the "4" and the "2f" are the denominators of the equations
