# Resonance Column Experiment

Classical Mechanics Level pending

While measuring the speed of sound by performing a resonance column experiment, a student gets the $$1^\text{st}$$ resonance condition at a column length of $$18$$ cm during the winter. Repeating the same experiment during summer, the student measures the column length to be $$x\text{ cm}$$ for the 3rd resonance. Then, choose the correct statement:
