A turning fork of frequency 600Hz is sounded over a closed resonance tube. If the first and second resonant positions are 0.130m and 0.413m respectively, calculate the speed of sound in air

In a resonance tube
L=wavelength/2
Wavelength=2×L
Since there are two resonant value
L=L¹-L²
L=0.413-0.130
=0.283
V=frequency ×lamda
V=600×0.283
V=339.6m/s

why is the f multiplied by 2??

I picked right answer but you missed it

Sorry multiply
0.283×2=0.566
Then use V=frequency ×wavelength
V=600×0.566
=339.6m/s

formular is v=f"/
:V= 600(0.413-0.1400
=163.8
