Question 112 of 142

While measuring the speed of sound by performing a resonance column experiment, a student gets the first resonance condition at a column length of $18 \mathrm{~cm}$ during winter. Repeating the same experiment during summer, she measures the column length to be $\mathrm{xcm}$ for the second resonance. Then

Answer: (B) $x\gt 54$

\begin{aligned} & n=\frac{1}{4 x} \sqrt{\frac{\gamma R T}{M}} \\ & x n=\frac{1}{4} \sqrt{\frac{\gamma R T}{M}} \\ & x \propto \sqrt{T} \end{aligned}
