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 cm during winter. Repeating the same experiment during summer, she measures the column length to be x cm for the second resonance. Then
Text Solution
Verified by ExpertsThe correct answer is:
A
During summer speed of sound increases. So wavelength increases.
so x > 3 × 18
so x > 54
