Question 185: 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$  ${{{\upsilon _0}} \over {{\upsilon _c}}} = {v \over {2\ell }} 	imes {{4\ell } \over v} = {2 \over 1}$
