$50\ \text{Hz}$ / $50\ \text{Hz}$
3.
$400\ \text{Hz}$ / $400\ \text{Hz}$
4.
$100\ \text{Hz}$ / $100\ \text{Hz}$
Correct Answer: $100\ \text{Hz}$ / $100\ \text{Hz}$
For a closed pipe, $f = v/4L = 340/(4 \times 0.85) = 100\ \text{Hz}$. / बंद पाइप हेतु $f = v/4L = 340/(4 \times 0.85) = 100\ \text{Hz}$।
