equation is f=v/4L
where did I go wrong what is my speed of sound in air

Answer 1

here you have taken wrong formula .

for one end open air column (for fundamental frequency)

  $L=\frac{\lambda }{4}$

so  $V=f\lambda \\ \Rightarrow V=4fL$

from this we get velocity of sound for 1st raw data =

$V=4\times 413.09\times 0.056\\ \Rightarrow V=92.53 \ m/s$

Now you can check for all data.
