Question

An open at both ends pipe has a length of 50cm. What are three lowest

frequencies to which it will resonate? v=340m/s]

Answer 1

$f=\frac{nv}{2L}$

$f_1=\frac{1\cdot 340}{2\cdot 0.5}=340\ (Hz)$

$f_2=\frac{2\cdot 340}{2\cdot 0.5}=680\ (Hz)$

$f_3=\frac{3\cdot 340}{2\cdot 0.5}=1020\ (Hz)$
