Question 397: Waves

Question

If the length of an open organ pipe is $$33.3 \mathrm{~cm}$$, then the frequency of fifth overtone is [Neglect end correction, velocity of sound $$=333 \mathrm{~m} / \mathrm{s}$$ ]

Accepted Answer

For a pipe open at both ends,
$$\mathrm{n}=\frac{\mathrm{v}}{21}=\frac{333}{2 	imes 33.3 	imes 10^{-2}}=500 \mathrm{~Hz}$$
$$	herefore \quad$$ Frequency of $$5^{	ext {th }}$$ overtone,
$$\mathrm{n}=6 \mathrm{n}=6 	imes 500=3000 \mathrm{~Hz}$$

Answer

$$3500 \mathrm{~Hz}$$

Answer

$$3000 \mathrm{~Hz}$$

Answer

$$2500 \mathrm{~Hz}$$

Answer

$$2000 \mathrm{~Hz}$$
