354950 Two open pipes of different lengths and same diameter in which the air column vibrates with fundamental frequencies ' \(n_{1}\) ' and ' \(n_{2}\) ' respectively. When both pipes are joined to form a single pipe, its fundamental frequency will be

1 \(\dfrac{n_{1}+n_{2}}{n_{1} n_{2}}\)
2 \(\dfrac{n_{1} n_{2}}{2 n_{2}+n_{1}}\)
3 \(\dfrac{2 n_{2}+n_{1}}{n_{1} n_{2}}\)
4 \(\dfrac{n_{1} n_{2}}{n_{1}+n_{2}}\)

354951 Assertion :
Sound produced by an open organ pipe is richer than the sound produced by a closed organ pipe.
Reason :
Outside air can enter the pipe from both ends, in case of open organ pipe.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
