we're supposed to figure out the relationship between the resonant length and the wavelength.

what we did was we filled up the resonant tube with water then put a tuning fork above it and found where that same sound was made.

Here is an example:

frequency of the tuning fork = 1024

1st resonant point:

resonant length: 7.8cm

0.23 ( lamda )

2nd resonant point: 24.5cm

0.72

and so on...

we figured out the resonant length in lamda by finding out velocity of sound in room temperature and finding out lamda by v/f

then resonant length (lamda) was figured out by res. length (cm) / wavelength (lamda)

now i have to figure out the relationship between the resonant length and the wavelength. first is the wavelength here referring to the wavelength figured out by v/f or lamda for resonant length?? is there a relation between the resonant length of the tube and the lamda resonant length?

can someone please help me figure out any kind of relationship here??
