हिन्दीThe ratio of frequencies of fundamental harmonic produced by an open pipe to that of closed pipe having the same length is :
Correct answer · Option 2
2 : 1
Explanation
Fundamental frequency of an open pipe is \( f_{open} = \frac{v}{2L} \) and for a closed pipe is \( f_{closed} = \frac{v}{4L} \). The ratio is \( \frac{f_{open}}{f_{closed}} = 2:1 \).
