हिन्दीAn air column, closed at one end and open at the other, resonates with a tuning fork when the smallest length of the column is \( 50\text{ cm} \). The next larger length of the column resonating with the same tuning fork is
Correct answer · Option 2
\( 150\text{ cm} \)
Explanation
For a closed pipe, resonating lengths are \( l_1 = \lambda/4 = 50\text{ cm} \). The next resonating length is \( l_2 = 3\lambda/4 = 3 \times 50 = 150\text{ cm} \).
