Question 240: Waves

Question

The fundamental frequencies of vibrations of air column in pipe open at both ends and in pipe closed at one end are ' $\mathrm{n}_1$ ' and ' $\mathrm{n}_2$ ' respectively, then

Accepted Answer

For a pipe open at both ends, the fundamental frequency is given by $\mathrm{n}_1=\frac{\mathrm{V}}{2 \mathrm{~L}}$
For a pipe closed at one end, the fundamental frequency is given by $\mathrm{n}_2=\frac{\mathrm{v}}{4 \mathrm{~L}}$
$$ 	herefore \quad \mathrm{n}_1=2 \mathrm{n}_2 $$

Answer

$\mathrm{n}_1=\mathrm{n}_2$

Answer

$\mathrm{n}_1=2 \mathrm{n}_2$

Answer

$\quad 2 n_1=n_2$

Answer

$3 n_1=4 n_2$
