Question 226: Waves

Question

Tube $$A$$ has bolt ends open while tube $$B$$ has one end closed, otherwise they are identical. The ratio of fundamental frequency of tube $$A$$ and $$B$$ is

Accepted Answer

KEY CONCEPT :
The fundamental frequency for closed organ pipe is given by $${\upsilon _c} = {v \over {4\ell }}$$ and
For open organ pipe is given by $${\upsilon _0} = {v \over {2\ell }}$$
$$	herefore$$  $${{{\upsilon _0}} \over {{\upsilon _c}}} = {v \over {2\ell }} 	imes {{4\ell } \over v} = {2 \over 1}$$
